You are on an interstate entrance ramp. Who has the right-of-way?
- A You, once your turn signal is on
- B You, because traffic must make room
- C Whoever is going faster
- D Drivers already on the interstate
Show answer
D. Drivers already on the interstate
When you are on an entrance or acceleration ramp, yield to drivers already on the limited-access or interstate highway. Drivers on the highway should make space when they safely can.
You plan to take the next interstate exit. When should you begin to slow down?
- A While still in the main travel lane, before the exit
- B After moving into the deceleration lane
- C Only once you reach the bottom of the ramp
- D A mile before the exit, in the left lane
Show answer
B. After moving into the deceleration lane
Move to the lane closest to your exit early, and keep your speed while on the main roadway. Signal, move into the deceleration lane, then check the posted speed and slow down.
On an interstate with steep hills and truck weigh stations, which lane does the manual suggest avoiding when possible?
- A The acceleration lane
- B The middle lane
- C The left lane
- D The right lane
Show answer
D. The right lane
Large trucks drive slowly, around 35 mph, on steep grades and use the right lane, and they re-enter traffic near weigh stations. Avoiding the right lane in these areas reduces the chance of a collision with a large vehicle.
