Right-of-way in one breath

Whoever arrives first at an uncontrolled or four-way stop goes first; if it's a tie, yield to the driver on your right. Pedestrians in any crosswalk always have the right-of-way. Emergency vehicles with lights and sirens always win — pull right and stop. Traffic already inside a roundabout has right-of-way over traffic entering it. When turning left, yield to all oncoming traffic and pedestrians first before completing the turn.

Top traps

• Treating the posted speed limit as always safe — in rain, fog, or on wet roads the safe speed is lower than the sign says
• Confusing yield-to-the-right with yield-to-whoever-arrived-first — arrival order comes first, the right-hand rule only breaks ties
• Assuming loud music or fresh air fixes drowsy driving — the only real fix is to stop and rest
• Forgetting that texting and handheld phone use are treated as serious distraction risks, not minor ones
• Not reviewing the handbook's signs-and-right-of-way chapter as one connected block — signs, signals, markings, and right-of-way are grouped together for a reason
• Skimming past school-zone and construction-zone signage, which the test uses to check judgment about reduced speeds during specific times or conditions
