2. How can a driver check whether they are keeping a safe following distance behind another vehicle?
Correct answer: By counting the seconds to reach a fixed reference point
A driver can pick a fixed reference point and count the seconds after the vehicle ahead passes it; reaching the point after three or more seconds shows a safe gap.
3. Why can driving much slower than the surrounding traffic be dangerous?
Correct answer: It leads other vehicles to keep passing you
Driving slower than the flow encourages other vehicles to keep passing you, which raises the chance of a crash.

Behind vehicles that stop often, a driver should increase the following distance to four or five seconds, or more if needed.
5. Which of the following affects how far it takes a driver to stop the vehicle?
Correct answer: The condition of the tires and brakes
Stopping distance depends on factors such as the driver's reaction time, the road's type and condition, the tire treads, and the condition of the brakes.
6. When leaving a limited-access highway, what is the deceleration lane used for?
Correct answer: To slow down safely toward the exit ramp
The deceleration lane leads to the exit ramp and gives a driver room to begin slowing to a safe speed after leaving the travel lanes.

11. What is the purpose of the acceleration lane when entering a limited-access highway?
Correct answer: To let you match the speed of highway traffic before merging

12. How does driving over the speed limit affect a vehicle's stopping ability?
Correct answer: It makes the vehicle take longer to stop
Higher speed means it takes longer to bring the vehicle to a stop and reduces the driver's ability to react to hazards.
