This section is the largest on the exam and focuses on defensive driving: staying alert, avoiding distractions (Arizona law prohibits holding a wireless device while driving), keeping a safe following distance, and using turn signals correctly.
Roundabouts and freeway rules come up often too — yield to traffic already in a roundabout and enter to the right of the center island, and when merging onto a freeway, match your speed to traffic without crossing a solid line or driving through a gore area.
A common mistake is misjudging when passing on the right is legal — it's only allowed when the other driver is turning left, or on a road clearly marked for two or more lanes in your direction; you should never pass on the right by driving off the paved roadway, and never pass within 100 feet of an intersection, railroad crossing, or bridge.
How does the 3-6 second rule work for following distance?⌄
When the vehicle ahead passes a fixed point, start counting; if you pass that same point before you finish counting to about four seconds, you're following too closely. Give yourself 3 to 6 seconds, increasing the cushion at faster speeds or in poor road conditions.
Who has the right-of-way when entering a roundabout?⌄
Vehicles already inside the roundabout have the right-of-way. As you approach, slow down and yield until there's a safe gap, then enter to the right of the center island.
When is it legal to pass another vehicle on the right?⌄
Only when the other driver is turning left, or on an open highway or business/residential district clearly marked for two or more lanes in your direction. You may never pass on the right by driving off the paved roadway.
