Questions and Answers

Practicing the Alberta CDL Class 4 Practice Test 4 you will learn the answers to the following questions that will help you pass the permit test:

Q1: What should you do if your car starts to skid?

  1. Stay calm: Keep a cool head and avoid panicking.
  2. Lift off the accelerator: Take your foot off the gas pedal to reduce speed.
  3. Steer in the direction you want to go: Turn the steering wheel gently in the direction you want the front of the car to go. Avoid oversteering.
  4. Do not brake suddenly: Avoid slamming on the brakes, as it can worsen the skid. If you have to brake, do so gently and with steady pressure.
  5. Shift to a lower gear (for manual transmission): If you are driving a manual vehicle, consider shifting to a lower gear to help slow down.
  6. Look where you want to go: Keep your eyes focused on the intended path and not on the obstacle or direction of the skid.

Remember, the key is to remain calm, lift off the accelerator, and steer in the desired direction to regain control of your vehicle. These tips apply to both regular driving situations and can be helpful during your permit test or CDL test in Canada.

Q2: What vehicle types are required to carry road flares or pylons in case the vehicle is disabled on the side of the road?

The requirement for carrying road flares or pylons can vary based on local regulations and the type of vehicle. However, certain types of vehicles, especially larger ones, are more likely to be required to carry such safety equipment. This may include:

  1. Commercial Vehicles: Trucks, buses, and other commercial vehicles are often required to carry safety equipment, including road flares or reflective triangles, in case of a breakdown or emergency on the side of the road.
  2. Commercial Drivers: Drivers with a commercial driver’s license (CDL) may be required to carry safety equipment in their commercial vehicles, as regulations for commercial drivers are generally more stringent.
  3. Emergency Vehicles: Certain emergency vehicles, such as tow trucks or service vehicles, may be required to carry road flares or pylons to enhance safety when they are assisting disabled vehicles.

It’s essential to check the specific regulations in the jurisdiction where the vehicle is operated, as requirements can vary. Additionally, personal vehicles may not be required to carry road flares or pylons, but it is always a good safety practice to have such equipment on hand in case of an emergency.

Before making a left turn, it’s crucial to follow proper procedures to ensure the safety of yourself and other road users. Here are the steps you should take before making a left turn:

  1. Signal:
    • Activate your left turn signal well in advance of the turn. This informs other drivers and pedestrians of your intention to make a left turn.
  2. Check Mirrors:
    • Check your rearview and side mirrors to be aware of the traffic behind you. Ensure there is enough space and time to make the turn safely.
  3. Check Blind Spot:
    • Look over your left shoulder to check your vehicle’s blind spot. This is especially important to spot any cyclists, pedestrians, or vehicles that may be in your blind spot and not visible in the mirrors.
  4. Position Your Vehicle:
    • Move your vehicle into the left lane or the left-turn lane if one is available. Position your vehicle closer to the center line, preparing for the turn.
  5. Yield to Oncoming Traffic:
    • Yield the right of way to oncoming traffic. Wait for a safe gap in traffic to make your left turn.
  6. Observe Pedestrians:
    • Watch for pedestrians crossing the street. Always yield to pedestrians in the crosswalk.
  7. Check Traffic Signal:
    • Observe the traffic signal at the intersection. Only proceed when you have a green light or a designated left-turn arrow.
  8. Turn Safely:
    • Once it is safe to proceed, turn the steering wheel smoothly to make the left turn. Be aware of any pedestrians, cyclists, or oncoming traffic.
  9. Complete the Turn:
    • Complete the turn into the appropriate lane on the intersecting road. Avoid cutting into the oncoming lane.

Remember to follow local traffic laws and regulations, as rules may vary by jurisdiction. Always exercise caution and be attentive to the surrounding traffic and pedestrians when making a left turn.

Q4: What are the pre-trip check steps?

Performing a pre-trip inspection is a crucial part of ensuring the safety and proper functioning of a vehicle before hitting the road. Below are general steps for a pre-trip check, which may vary slightly depending on the type of vehicle (e.g., personal vehicle, commercial vehicle, truck, or bus).

This is a basic guide, and specific requirements can vary based on local regulations and the type of vehicle. For commercial vehicles like trucks and buses, drivers often use a formal checklist provided by the relevant authorities or their company. Here are the key steps:

1. Exterior Inspection:

  • Lights: Check that all lights are working, including headlights, taillights, brake lights, turn signals, and hazard lights.
  • Reflectors: Ensure that reflectors are clean and visible.
  • Tires: Inspect tire condition, including tread depth and inflation. Check for any visible damage.
  • Wheels and Rims: Examine wheels and rims for damage.
  • Suspension: Check for visible damage or leaks.
  • Brakes: Inspect brake components for wear, damage, and proper function.

  • Check Gauges: Monitor dashboard gauges for any abnormalities.

5. In-Cab Inspection:

  • Controls: Test various controls, including lights, wipers, turn signals, and HVAC.
  • Emergency Equipment: Ensure required emergency equipment (fire extinguisher, warning triangles, etc.) is present and in good condition (for commercial vehicles).

Completing a thorough pre-trip inspection helps identify potential issues before they become serious problems, promoting safety on the road. Always refer to the specific guidelines provided by the relevant authorities or your company for the type of vehicle you are inspecting.

Q5: Where does a large vehicle have blind spots?

Large vehicles, such as trucks and buses, have significant blind spots due to their size and design. These blind spots are areas around the vehicle where the driver has limited or no visibility. Drivers of these large vehicles must be aware of these blind spots to avoid accidents with other vehicles, pedestrians, or cyclists. The typical blind spots for large vehicles include:

  1. Directly Behind the Vehicle:
    • The area immediately behind the truck or bus is a significant blind spot. The driver cannot see vehicles or objects directly behind the vehicle using mirrors.
  2. In Front of the Vehicle:
    • Large vehicles often have a high front hood, leading to limited visibility of smaller vehicles or obstacles directly in front of the truck or bus.
  3. Driver’s Side Blind Spot:
    • The left side of the vehicle, especially towards the rear, is a common blind spot. This area may not be visible in the side mirrors.
  4. Passenger Side Blind Spot:
    • The right side of the vehicle, particularly towards the rear, is another blind spot. This area may not be visible in the side mirrors.
  5. Blind Spots Along the Length of the Vehicle:
    • The entire length of a large vehicle, especially the trailer portion of a truck, can create blind spots along the sides. These areas may not be fully visible in the side mirrors.

To minimize the risks associated with blind spots, it’s essential for drivers of large vehicles to:

  • Adjust mirrors properly to maximize visibility.
  • Perform shoulder checks and use convex (wide-angle) mirrors to check blind spots.
  • Be cautious when changing lanes or making turns, especially in heavy traffic.
  • Use turn signals well in advance to alert other road users of their intentions.

Drivers of smaller vehicles sharing the road with large vehicles should also be aware of these blind spots and avoid lingering in them. If you can’t see the driver’s face in their side mirrors, likely, that they can’t see you.

Increased awareness and communication on the road can contribute to safer driving conditions for all vehicles.

Q6: When performing a turnaround with a school bus, the correct procedure is to?

When performing a turnaround (also known as a U-turn) with a school bus, it’s important to follow proper procedures to ensure the safety of the passengers and other road users. The specific guidelines may vary based on local regulations and policies, but here is a general procedure for making a turnaround with a school bus:

  1. Choose a Safe Location:
    • Select a location that allows for a safe and legal turnaround. Ensure there is enough space for the bus to maneuver without obstructing traffic.
  2. Activate Flashers:
    • Turn on the school bus’s flashing amber warning lights to alert other drivers that the bus is preparing to stop.
  3. Check for Traffic:
    • Check for oncoming traffic from both directions. Ensure there is enough time and space to complete the turnaround safely.
  4. Signal Intentions:
    • Activate the bus’s left turn signal to indicate your intention to make a left turn or U-turn.
  5. Stop the Bus:
    • Bring the bus to a complete stop. Ensure that the stop is made at a safe distance from any intersections or obstacles.
  6. Check for Pedestrians:
    • Look for pedestrians and ensure they are clear of the bus’s path before proceeding with the turnaround.
  7. Check for Oncoming Traffic Again:
    • Double-check for oncoming traffic from both directions. Make sure there is a safe gap to execute the turnaround.
  8. Execute the Turnaround:
    • Make the left turn or U-turn smoothly, taking into consideration the size and length of the school bus. Use the entire width of the road to complete the maneuver safely.
  9. Check Blind Spots:
    • Be aware of blind spots and check mirrors to ensure there are no vehicles, pedestrians, or obstacles in the bus’s path.
  10. Complete the Turnaround:
    • Once the turnaround is completed safely, deactivate the left turn signal and resume driving in the appropriate direction.
  11. Deactivate Flashers:
    • If applicable, deactivate the flashing amber warning lights once the bus is back on its route and moving in the intended direction.

School bus drivers must follow local traffic laws and adhere to any additional guidelines provided by their school district or transportation authority. Additionally, drivers should always prioritize the safety of the passengers and other road users during such maneuvers.

Q7: Should you make eye contact with cyclists around your vehicle?

Making eye contact with cyclists around your vehicle is an important safety practice. When you make eye contact with cyclists, it helps establish communication and ensures that both you, as the driver, and the cyclist are aware of each other’s presence. This is particularly crucial in situations where cyclists may be in your vehicle’s blind spots, such as when turning or changing lanes.

Here are some reasons why making eye contact with cyclists is important:

  1. Visibility: Cyclists can be harder to see, especially in blind spots. Making eye contact confirms that the cyclist is aware of your presence and intentions.
  2. Communication: Eye contact is a form of non-verbal communication. It can signal to the cyclist that you see them and intend to take a particular action, such as yielding the right of way or making a turn.
  3. Safety: Establishing eye contact helps prevent misunderstandings and reduces the risk of accidents. It allows both parties to anticipate each other’s movements.

When interacting with cyclists, especially in urban or crowded areas, remember these tips:

  • Check your blind spots carefully before turning or changing lanes.
  • Use your turn signals to indicate your intentions well in advance.
  • Make eye contact with cyclists when possible.
  • Give cyclists enough space when passing them on the road.

Overall, being attentive and making eye contact with cyclists contributes to a safer road environment for everyone. It’s an essential part of sharing the road responsibly and reducing the risk of accidents involving cyclists and motor vehicles.

Communication and Phone Mounts

Safety on the road is paramount, and a sturdy phone mount is a must-have for drivers who rely on navigation apps or need hands-free communication. Look for mounts that attach securely to the dashboard or windshield and are adjustable to accommodate different phone sizes.

Q8: How far back should you stay when following an emergency vehicle?

When following an emergency vehicle, it’s important to maintain a safe distance to ensure both your safety and the safety of the emergency responders and the vehicles they are assisting.

The recommended distance may vary based on local regulations and the specific circumstances, but a general guideline is to stay at least 500 feet (about 150 meters) behind an emergency vehicle with its lights and sirens activated.

Maintaining a safe following distance allows the emergency vehicle to have a clear path and provides you with enough time and space to react to unexpected maneuvers or stops. Additionally, emergency vehicles may need to make sudden lane changes or navigate through traffic, so giving them ample room is essential.

Q9: What describes a “special vehicle”?

The definition may vary depending on the context, regulations, and local laws. Here are a few examples of what might be considered a “special vehicle” in different contexts:

  1. Emergency Vehicles: Police cars, ambulances, fire trucks, and other vehicles used by emergency services are often referred to as special vehicles. They are equipped with features and equipment to respond quickly to emergencies.
  2. Military Vehicles: Vehicles used by the military for various purposes, such as tanks, armored personnel carriers, and military trucks, are considered special vehicles due to their specific design and functionality.
  3. Construction Vehicles: Vehicles designed for construction purposes, such as bulldozers, excavators, and cranes, fall under the category of special vehicles. They are equipped with tools and machinery for construction and heavy-duty tasks.
  4. Agricultural Vehicles: Farm equipment such as tractors, combines, and harvesters are considered special vehicles designed for agricultural activities.
  5. Recreational Vehicles (RVs): Motorhomes, camper vans, and other recreational vehicles are often categorized as special vehicles because they are designed for both transportation and living accommodations.
  6. Special Purpose Vehicles: Some vehicles are modified or designed for specific tasks, such as mobile command centers, mobile clinics, or mobile laboratories. These are considered special purpose or special vehicles.
  7. Hearse: A vehicle designed for the transportation of deceased individuals, often used during funeral services, is considered a special vehicle.

The definition of a special vehicle can vary based on the legal and regulatory framework in a specific region.

Q10: When can you use the flashing red lights and sirens on an ambulance?

The use of flashing red lights and sirens on an ambulance is reserved for emergencies when the vehicle is responding to a call for assistance. The primary purpose of activating these lights and sirens is to alert other road users and pedestrians, indicating that the ambulance is on an urgent mission and has the right of way.

Ambulances use flashing red lights and sirens in the following situations:

  1. Emergency Responses: When responding to an emergency call, such as a medical emergency, accident, or other life-threatening situations, ambulances use lights and sirens to quickly navigate through traffic and reach the scene as promptly as possible.
  2. Transporting Patients: When transporting a patient who requires urgent medical attention, ambulances may continue to use lights and sirens to ensure a swift and unobstructed journey to the hospital or medical facility.
  3. Interfacility Transfers: Ambulances may use lights and sirens during interfacility transfers when transporting patients between medical facilities, especially if the patient’s condition requires immediate attention.

Other drivers on the road need to be aware of and respond appropriately to the presence of an ambulance with activated lights and sirens. In many jurisdictions, drivers are legally required to yield the right of way to emergency vehicles and take necessary actions to allow them to pass safely.

However, emergency responders are trained to navigate traffic cautiously and responsibly, even when using lights and sirens, to minimize the risk of accidents. In non-emergency situations, ambulances typically operate with normal traffic rules, without the use of lights and sirens.

Q11: When driving in bad weather, what should your following distance be?

When driving in bad weather conditions, such as rain, snow, ice, or fog, it’s crucial to increase your following distance to ensure a safe driving experience. The general rule of thumb is to at least double the normal following distance recommended for ideal driving conditions. This increased following distance allows for more time to react and maneuver in case of sudden stops or emergencies.

In ideal driving conditions, the recommended following distance is typically 3 to 4 seconds. However, in adverse weather conditions, you should aim for a following distance of 6 to 8 seconds or more. To determine your following distance:

  1. Select a fixed point: Choose a specific point on the road, such as a road sign or a landmark, that the vehicle in front of you passes.
  2. Count the seconds: Once the vehicle in front of you passes the chosen point, start counting the seconds it takes for your vehicle to reach the same point. In bad weather, aim for a count of at least 6 to 8 seconds.

Factors that may influence the need for a longer following distance in bad weather include reduced visibility, slippery road conditions, and the potential for longer stopping distances.

Remember these additional tips for driving in bad weather:

  • Reduce your speed: Driving at a speed appropriate for the weather conditions is crucial. Slow down to allow for better control and increased reaction time.
  • Use headlights: Keep your headlights on, even during the day, to enhance visibility for yourself and other drivers.
  • Avoid sudden maneuvers: Sudden movements can lead to loss of control, especially on slippery surfaces. Make gradual turns and stops.
  • Stay informed: Be aware of weather forecasts and road conditions before starting your journey. Consider delaying travel if weather conditions are severe.

Q12: Why should you do a shoulder check when making a right turn?

Performing a shoulder check when making a right turn is a crucial safety practice because it helps you be aware of any potential hazards in your vehicle’s blind spot. The blind spot is an area around your vehicle that is not visible in the mirrors, and it is especially important to check before making a right turn. Here are the main reasons why a shoulder check is necessary:

  1. Check for Bicyclists and Motorcyclists:
    • Bicyclists and motorcyclists are more vulnerable road users and may be traveling in the bike lane or along the right side of the road. A shoulder check ensures that you are not turning into their path.
  2. Verify the Presence of Pedestrians:
    • Pedestrians may be crossing the street from your right side, especially at intersections. A shoulder check helps confirm that there are no pedestrians in your blind spot.
  3. Avoid Collisions with Vehicles in the Adjacent Lane:
    • Before changing lanes to make a right turn, it’s essential to check for vehicles in the adjacent lane to ensure you won’t cut them off or cause a collision.
  4. Ensure Safe Lane Change:
    • If you need to merge into the bicycle lane before making a right turn, a shoulder check ensures that it is safe to do so. This is important for compliance with traffic rules and for the safety of cyclists.
  5. Prevent Right-Hook Collisions:
    • A “right-hook” collision can occur when a driver turns right without checking the blind spot, and there is a cyclist or pedestrian in the path of the turn. A shoulder check helps prevent such collisions.

To perform a shoulder check when making a right turn:

  • Signal your intention to turn right: Activate your right turn signal well in advance.
  • Check your rearview mirror: Assess the traffic behind you.
  • Perform a right-side mirror check: Check the right-side mirror for any vehicles or cyclists.
  • Perform a shoulder check: Turn your head and look over your right shoulder to check the blind spot.
  • Complete the turn when clear: Proceed with the right turn only when you are confident that the path is clear.

By incorporating a shoulder check into your right-turn procedure, you enhance your awareness of potential risks, making the maneuver safer for you and other road users.
