What is the Guam speed limit?

Guam traffic laws define the maximum speed that any motorist travelling on Guam roadways can legally drive. Driving over the Guam speed limit can result in a traffic citation, fine, license suspension, or even arrest.

The main road on Guam is Marine Corps Drive/Guam Route 1, aka Marine Drive. The maximum posted speed limit for the entire island is 35mph. However, most people drive faster than this. Some of the roads become unusually slippery when wet because they’re paved with coral aggregate. Guam has a much higher rate of accidents per 1,000 people than the continental U.S.

Guam has a relatively low maximum speed limit. There are a total of 52 states that have higher maximum speed limits than the Guam top speed of 45 miles per hour.



Guam Speed Limit - Divided Roads

The maximum speed limit on divided roads in Guam is 45 miles per hour. Divided roads must have a concrete median or buffer zone separating opposite lanes, and may have one or more lanes going in the same direction.

Unlike many states that allow higher speed limits on divided roads, Guam has the same maximum speed limit for both divided and undivided roads.



Guam Speed Limit - Undivided Roads

The maximum speed limit on rural undivided roads roads in Guam is 45 miles per hour. This category includes most small backroads and local routes.

When these routes pass through a residential or heavily-trafficked area, the speed limit will usually drop to 35 mph or below.



Guam Speed Limit - Residential Areas

The maximum speed limit on residential roads in Guam is 35 miles per hour. Residential roads have the most potential for speed-based accidents and collisions, so residential districts tend to have the lowest speed limits with the most strict enforcement policies.

When driving in residential areas be on the lookout for school, hospital, and construction zones. These areas often have even lower speed limits, with strict enforcement and heavy fines for speeding.

Guam Speeding Tickets and Citations

Driving over the posted speed limit, driving too fast for conditions, or failing to obey special speed limit zones can result in a Guam speeding ticket, points on your license, and even a license suspension or revocation for repeat offenders.

Guam highway patrol officers monitor traffic using radar, speed traps, and cameras. Radar technology is not exact, and as a general rule an officer will not pull you over for exceeding the speed limit by less than 5 mph (5 mph on a rural freeway, or 50 mph on an rural undivided road). However, any speeds in excess of the posted speed limits can be considered a ticketable offence.
