You are driving a car, not towing anything, on a two-lane highway posted at 55 mph. Outside any work zone, you pass a truck going 45. How much over the limit may you go while passing?
- A Up to 10 mph, then slow back to the limit
- B Up to 20 mph, then slow back to the limit
- C Up to 15 mph, then slow back to the limit
- D Not at all; you must stay at or below 55 mph
Show answer
C. Up to 15 mph, then slow back to the limit
In a passenger vehicle, motorcycle or pickup not towing, you may exceed the limit by up to 15 mph to pass a slower vehicle on a two-lane road posted 55 mph or higher. It does not apply in work zones, and you must return to the limit as soon as practicable.
