Question

when exiting a highway, you should slow down:

on the main road, just before the exit lane.
once you have moved into the exit lane.
once you see the toll booth.
when you first see the exit sign.

Explanation:

Identify the core driving rule

This question asks about the safe procedure for reducing speed when exiting a highway. Applying Driver Education principles, slowing down on the main highway lanes can disrupt the flow of traffic behind you and cause rear-end collisions.

Evaluate the options

• on the main road, just before the exit lane: Incorrect. This forces high-speed highway traffic behind you to slow down abruptly.
• once you have moved into the exit lane: Correct. The exit lane (deceleration lane) is specifically designed to allow drivers to reduce speed safely off the main highway.
• once you see the toll booth: Incorrect. This is too late and can lead to unsafe speeds on the ramp.
• when you first see the exit sign: Incorrect. This is too early and would cause you to slow down on the main highway.

Formulate the final conclusion

The safest practice is to maintain highway speed until you fully enter the deceleration/exit lane, and then reduce your speed to match the posted ramp limit.

Answer:

• on the main road, just before the exit lane.
• once you have moved into the exit lane. (Correct answer)
• once you see the toll booth.
• when you first see the exit sign.
