The infraction or offense of speeding in a construction or work zone is committed when the driver of a motor vehicle in a marked construction/work zone exceeds the posted speed limit or exceeds the speed limit that is reasonable and prudent under the circumstances or conditions—conditions such as the road (straight, curved, wet, dry, icy, flat, hilly); the weather (clear, foggy, raining, snowing); and the visibility (smoke from a grass fire or a tractor trailer obstructing the view).

Laws vary from state to state and in many states the construction or work zone speed limit only applies when workers are present and the zone is clearly marked with signs. But drivers should be aware that the construction or work zone often extends past where barrels or other barriers have been placed on the road and the reduced speed limit continues to apply until there is a sign indicating an increased speed limit.

Laws regarding speeding in a construction or work zone (and their enforcement) vary from state to state and among cities and towns (local ordinances) and are usually located in a state’s statutes. The penalty for speeding in a construction or work zone is usually a fine and demerit points added to the driver’s license or driving record. But the fines and penalties for speeding in a construction zone are usually much greater than for a typical speeding ticket or citation—for example, fines may be doubled.

In Wyoming, the offense of speeding in a construction or work zone is taken very seriously due to the increased risk to workers and the public. The state enforces specific regulations that require drivers to adhere to posted speed limits within these zones. These limits are in place regardless of whether workers are present, as the conditions of the road may still be altered or hazardous due to ongoing work. Wyoming law stipulates that fines for speeding in a construction zone are typically higher than for regular speeding violations. This is to deter drivers from endangering lives and to maintain safety within the work zone. Additionally, drivers who are caught speeding in these areas may also receive demerit points on their driving record, which can affect their driving privileges. It's important for drivers to pay close attention to signage indicating the start and end of construction zones to ensure compliance with the speed limits and to avoid the increased penalties associated with these infractions.
