Show answer
Answer B: Wait and let that driver finish the turn
A vehicle that has lawfully started a maneuver keeps the right of way until it is finished.

17. On a highway with mileage-based exit numbering, you have just passed exit 42 and are looking for exit 55. About how far is it?
Show answer
Answer B: Thirteen miles
With mileage-based numbering each exit takes the number of the nearest milepost, so subtracting one exit number from another gives the distance in miles.

18. A driver in the leftmost lane reaches this sign at an intersection. What must the driver do?
Show answer
Answer B: Go straight on or turn right, and reach the destination another way

Show answer
Answer A: To reduce the risk of a fire starting around any fuel that has spilled
Crashes often break fuel lines, and a running engine is a source of ignition, so switching off lowers the risk of fire.
