Indiana Bureau of Motor Vehicles Permit Practice Test

What is the maximum speed limit in a highway work zone?

1. 30 mph

2. 40 mph

3. 45 mph

4. 55 mph

The correct answer is: 45 mph

In highway work zones, the maximum speed limit is typically reduced to ensure the safety of both workers and motorists. The most common maximum speed limit in such zones is 45 mph. This speed is considered a balance between maintaining traffic flow and enhancing safety conditions, as workers may be present close to the roadway, and vehicles may need to navigate around barricades, equipment, or other obstacles. While you may come across varying speed limits depending on the specific work zone or any signs posted, the 45 mph limit is widely recognized and commonly enforced in Indiana. Lower limits, such as 30 or 40 mph, can also be found, but they are less standard than the 45 mph limit. A speed limit of 55 mph is typically considered too high for a work zone due to increased risks associated with potential hazards posed by construction activities and personnel. Being aware of the speed limit changes in work zones is crucial for your safety and compliance as a driver. Always look for posted signs that may indicate lower speed limits specific to the work zone you encounter.
