2025 Guam Driving Practice Test – The Complete All-in-One Guide to Passing Your Exam!

The maximum lawful speed limit in Guam, unless otherwise posted, is indeed 45 miles per hour. This speed limit serves as a standard guideline for most roadways within the territory, helping to ensure safety for all road users, including pedestrians and cyclists.

Understanding this speed limit is important for safe driving practices, as it provides a baseline for speed regulation unless indicated otherwise by posted signage. This means that on roads where no specific speed limit signs are displayed, drivers must adhere to the 45 miles per hour limit.

In terms of traffic regulation, exceeding this speed could lead to safety hazards such as reduced reaction times and increased stopping distances, which may result in accidents. Therefore, knowing the default speed limits helps drivers make informed decisions while navigating Guam's roads.
