ELDT - Entry Level Driver Training Speed and Space Management Questions and Answers 1 — Questions and Answers
Question 1: According to the Federal Motor Carrier Safety Administration (FMCSA) guidelines, what is the recommended minimum following distance for a 60-foot tractor-trailer traveling at 55 mph under ideal conditions?
- 4 seconds
- 5 seconds
- 7 seconds (Correct answer)
- 10 seconds
Correct answer: 7 seconds
The FMCSA recommends one second of following distance for every 10 feet of vehicle length when traveling under 40 mph. For speeds over 40 mph, an additional second should be added. For a 60-foot truck, this is 6 seconds, plus 1 additional second for traveling over 40 mph, totaling 7 seconds.
Question 2: A driver is operating a commercial motor vehicle in heavy rain, which has reduced visibility and made the road surface slick. How should the driver adjust their speed and space management?
- Maintain the posted speed limit and normal following distance.
- Increase speed slightly to get through the adverse conditions faster.
- Reduce speed and at least double the normal following distance. (Correct answer)
- Engage cruise control to maintain a steady speed.
Correct answer: Reduce speed and at least double the normal following distance.
In adverse conditions such as rain, snow, or fog, a driver must reduce their speed and increase their following distance to account for longer stopping distances and reduced visibility. The FMCSA recommends doubling the following distance in such conditions.
Question 3: Total stopping distance for a commercial motor vehicle is a combination of three factors. Which of the following correctly lists these three factors?
- Driver alertness, brake temperature, and tire pressure.
- Perception distance, reaction distance, and braking distance. (Correct answer)
- Vehicle weight, road grade, and speed.
- Following distance, brake lag, and driver skill.
Correct answer: Perception distance, reaction distance, and braking distance.
Total stopping distance is calculated by adding three key components: Perception Distance (the distance traveled from seeing a hazard to recognizing it), Reaction Distance (the distance traveled from recognizing the hazard to applying the brakes), and Braking Distance (the distance traveled after the brakes are applied until the vehicle stops).
Question 4: When making a right turn in a long vehicle, what is the primary reason for not swinging wide to the left before initiating the turn (a 'jug handle' turn)?
- It uses too much fuel.
- It can confuse other drivers, who may try to pass on the right. (Correct answer)
- It is illegal in all 50 states.
- It puts unnecessary stress on the tires and suspension.
Correct answer: It can confuse other drivers, who may try to pass on the right.
Swinging wide to the left before a right turn can signal to other drivers that you are turning left or changing lanes. This can invite a vehicle to attempt to pass on your right side, placing them in your blind spot and in the path of your turning trailer, which can lead to a collision.
Question 5: Which of the following is the most critical aspect of managing the space *behind* your commercial vehicle?
- Frequently tapping your brakes to warn tailgaters.
- Slowing down abruptly to create more space.
- Avoiding sudden changes in speed and staying to the right when possible. (Correct answer)
- Using your hazard lights whenever a vehicle is following too closely.
Correct answer: Avoiding sudden changes in speed and staying to the right when possible.
While a driver cannot control who is behind them, they can manage the situation by maintaining a steady speed and staying in the right-most lane when practical, which encourages tailgaters to pass. Sudden actions can startle the other driver and increase the risk of a rear-end collision.
Question 6: A commercial driver needs to back into a loading dock. What is the most important first step according to the principle of 'Get Out And Look' (G.O.A.L.)?
- Turn on hazard lights and sound the horn continuously.
- Get out of the cab to survey the area for obstacles and clearances.
- Rely solely on mirrors and backup cameras to check the path. (Correct answer)
- Immediately begin backing slowly while watching mirrors.
Correct answer: Rely solely on mirrors and backup cameras to check the path.
The G.O.A.L. principle requires the driver to physically get out of the vehicle and walk around it to check for any hazards, obstacles, overhead clearances, and the overall path before beginning any backing maneuver. This helps identify blind spots that mirrors and cameras might miss.
