When driving on the highway what should be your speed?

  1. 25 mph

  2. 45 mph

  3. 65 mph

  4. 85 mph

The correct answer is: 65 mph

The recommended speed limit for driving on a highway is 65 miles per hour. This speed allows you to safely keep up with the flow of traffic and react to any unexpected situations that may arise. Option A is too slow for a highway, which may cause cars behind you to become impatient and could create a traffic hazard. Option B is also too slow and could pose a hazard as other drivers tend to travel at or around the speed limit. Option D is too fast and can increase your chances of losing control of your vehicle or not being able to stop in time in case of an emergency. Therefore, the best speed to drive on a highway is 65 mph.
