Guam Road Signs Practice key terms

A sign that gives an order or sets a rule drivers must obey, such as a speed limit, stop, yield, or turn restriction. Disobeying one is a traffic violation.

A white rectangular sign with black lettering showing the maximum legal speed in miles per hour on that road under normal conditions. Slower speeds are required when conditions are poor.

A red octagon with white letters requiring a complete halt at the stop line or crosswalk, yielding to pedestrians and cross traffic before proceeding. A rolling stop is a violation.

A red and white downward-pointing triangle telling drivers to slow down and give the right of way to traffic on the intersecting road, stopping only if necessary.

A red square with a white horizontal bar and the words DO NOT ENTER, marking a roadway entrance where traffic may not proceed, often the exit ramp of a one-way road.

A black horizontal arrow on a white rectangle showing that traffic on that roadway moves only in the direction of the arrow. Entering against the arrow is illegal.

A red rectangle with white letters reading WRONG WAY, posted on exit ramps and one-way roads to warn drivers they are heading into oncoming traffic. Stop and turn around immediately.

A regulatory sign prohibiting leaving a vehicle unattended along the curb or shoulder it governs, often during posted hours. Violations can lead to towing or a citation.

The standard shape for warning signs in the United States, used so drivers can recognize a hazard warning by shape alone even before reading the symbol or words.

A yellow rectangular plaque mounted below a warning sign showing a recommended safe speed for the hazard, such as a sharp curve. It is a suggestion, not the legal speed limit.

A yellow diamond showing a curved arrow, indicating a bend ahead. A sharper bend or a reverse curve may be shown with a different arrow symbol or an advisory speed.

A yellow diamond showing two arrows joining, warning that traffic from another lane or ramp will enter your roadway. Adjust speed and position to allow a safe merge.

A brown sign with white lettering pointing to parks, historic sites, campgrounds, and other recreation areas. It is informational only and sets no rule.

An orange diamond or rectangular sign warning of road work, lane changes, or workers ahead. Orange is reserved for temporary traffic control, so expect changed conditions and reduced speed.

A posted speed limit, often on an orange sign, applied while construction is active. Fines for speeding in work zones are commonly doubled when workers are present.

A worker using a sign or hand signals to alternate traffic through a work zone. Drivers must obey the flagger, who controls the right of way in place of signals or signs.
