You can see a marking on a vehicle ahead of you which is a red triangle with an orange center. What does the marking mean?

  1. School bus in operation

  2. Medical emergency vehicle approaching

  3. Road work ahead

  4. It may be a slow-moving vehicle

The correct answer is: It may be a slow-moving vehicle

The correct answer indicates that the red triangle with an orange center is a universal symbol for slow-moving vehicles. This marking is specifically designed to alert other drivers that the vehicle ahead may not be traveling at normal highway speeds, typically under 25 miles per hour. These vehicles often include agricultural equipment, construction vehicles, or any other type of vehicle that can impede the flow of traffic due to their limited speed capability. Recognizing this sign helps maintain safety on the roads, allowing drivers to anticipate the need to slow down or change lanes as necessary.
