California DMV Permit Test (Class C)Safe Driving PracticesMedium

You are driving on a road with a speed limit of 55 mph. If you are towing a trailer, what is the maximum speed you are legally allowed to drive in California, unless otherwise posted?

  1. A45 mph
  2. B50 mph
  3. C65 mph
  4. D55 mph
Show answer & explanation

Correct answer: D. 55 mph

In California, vehicles towing a trailer or another vehicle, or a bus or three-axle truck, are generally restricted to a maximum speed of 55 mph, even if the posted speed limit for other vehicles is higher. This is a specific regulation for these types of vehicles.

Why the other options are wrong

  • A. 45 mph is too low for a general maximum when towing, though again, specific conditions might warrant it.
  • B. 50 mph is too low for a general maximum when towing, although specific conditions or postings might require it.
  • C. 65 mph is for passenger vehicles on certain freeways; it does not apply to vehicles towing trailers.
