Before backing from a residential parking space, what should you do?
Correct answer: Check behind before entering, look directly to the rear, and back slowly.
Children and small objects may be hidden from the seat. Inspect the area, look over your shoulder and continue looking back until stopped.

You enter a freeway using an acceleration lane. Who has the yielding duty at the merge?
Correct answer: You must yield to traffic already on the freeway and choose a safe gap.
Adjust speed to blend safely, signal and check the gap. The entering driver must yield rather than force a freeway vehicle to avoid a crash.

A short acceleration lane and heavy traffic leave no safe merging gap. What should you do?
Correct answer: Slow or stop if necessary, leaving room to accelerate when a safe gap opens.
Some entrances require slowing or stopping when no safe opening exists. Leave room to accelerate and enter only without interfering with freeway traffic.

You pass your intended freeway exit. What should you do?
Correct answer: Continue to the next exit and use a lawful route back.
Backing is prohibited on controlled-access highways, including shoulders. Never use a missed exit as a reason to back or turn across the median.

Why should you use the exit's deceleration lane before making the main reduction to ramp speed?
Correct answer: It lets you slow without disrupting the through-traffic flow.
Choose the exit lane in advance, signal and use the deceleration lane to reduce speed smoothly for the ramp.

A signed thru-turn intersection prohibits a direct left turn. What route does the handbook describe for completing that movement?
Correct answer: Go through, make the directed downstream U-turn, return and turn right.
A thru-turn relocates the left-turn movement. Follow the designated downstream U-turn and then return for a right turn instead of making a direct left.

You mistakenly exit a freeway at the single-point urban interchange described in the handbook. Can you simply drive straight across the intersecting highway and reenter on the other side?
Correct answer: No; turn onto the intersecting highway and find a safe lawful place to turn around.
The handbook explains that this interchange's exit does not provide that straight-across reentry movement. Follow its lane controls and use a lawful route to the correct entrance.

A diverging diamond interchange temporarily guides your lane onto the left side of the roadway. What should you do?
Correct answer: Follow the controlled lane path and signals through both crossovers.
A DDI intentionally transfers traffic to the left and then back to the right. Follow the signals, signs and lane guidance; do not improvise across islands.
