Sign shapes at a glance

• Octagon (red) = stop
• Downward triangle (red/white) = yield
• Pentagon = school zone/crossing
• Diamond (yellow) = general warning ahead
• Round (yellow) = railroad crossing
• Rectangle (white) = regulatory (speed, one-way, turns)
• Rectangle (green) = guide/direction
• Diamond/rectangle (orange) = construction/work zone
• Rectangle (blue) = motorist services
• Rectangle (brown) = recreational/cultural sites

Right-of-way in one breath

First to arrive at an uncontrolled intersection goes first; simultaneous arrivals yield to the right. Left turns yield to oncoming traffic and pedestrians, even on green. T-intersection traffic yields to the through road. Pull right and stop for any emergency vehicle running lights/siren. Pedestrians in any crosswalk, marked or unmarked, have the right-of-way. In roundabouts, yield to traffic already circulating.

Top traps

• "Green light means go": not if you're turning left across oncoming traffic or a pedestrian is still in the crosswalk.
• Confusing sign color with sign shape: shape is the more reliable cue at a distance or in bad light — an octagon is a stop sign even if the paint has faded.
• Treating posted speed as a floor, not a ceiling: it's a maximum; rain, fog, or heavy traffic require driving below it.
• Assuming DUI is only about alcohol: impairment from medication or drugs carries the same consequences as crossing the 0.08% BAC line.
• Skipping equipment-law questions: window tint below 32% light transmission is a real test topic, not a footnote.
• Cramming instead of practicing: run full timed practice tests and track misses by category — sign recognition and right-of-way scenarios are where most points are actually lost.
