California DMV Permit Test (Class C)Safe Driving PracticesMedium
You are preparing to exit a freeway. When should you begin to slow down?
- AAfter you have entered the deceleration lane.
- BImmediately upon seeing the exit sign.
- CBefore you enter the deceleration lane, while still on the freeway.
- DAs you begin to turn off the freeway onto the exit ramp.
Show answer & explanationAnswer & explanation
Correct answer: A. After you have entered the deceleration lane.
You should maintain your speed while still on the main freeway lanes. Begin to slow down only after you have fully entered the deceleration lane (also known as an exit ramp or off-ramp) to avoid disrupting the flow of freeway traffic and creating a hazard.
Why the other options are wrong
- B. Slowing down on the freeway itself can cause a rear-end collision for following traffic.
- C. Slowing down on the freeway before the deceleration lane is dangerous.
- D. Beginning to slow down only as you turn onto the ramp is too late and may require abrupt braking, which is unsafe.
Freeway Exiting
The correct procedure for safely exiting a freeway.
- Maintain freeway speed until in deceleration lane.
- Begin slowing down only in the deceleration lane.
- Deceleration lane allows smooth speed reduction.
Memory trick: Stay fast on the freeway, then slow on the ramp, don't cause a traffic tramp.
