The numbers everyone forgets
Most missed traffic-law questions involve a specific number. Turn signal must be on for the last 100 feet before the turn in most states. Parallel-parked cars must be within 6 to 12 inches of the curb. You must be able to see persons or vehicles 1,000 feet ahead before you can drive without headlights. You must stay back 500 feet from emergency vehicles responding with lights and siren. Memorize these.
Cell phones and new drivers
Cell phone laws are stricter for new drivers than for adults. In many states a learner or intermediate license holder cannot use a phone at all behind the wheel, including hands-free, while a fully licensed adult is only banned from holding the phone. The test is checking the new-driver rule, not the adult rule.
Watch for absolute words
Multiple-choice traffic law questions often hide their trick in absolute words. 'Always,' 'never,' and 'only' are usually the wrong answer. Look for choices that include conditions like 'when conditions allow' or 'unless otherwise posted' — those answers tend to match how the law actually works.
Parking on hills, parking with a curb
The hill-parking question shows up almost every test. Facing downhill with a curb, turn the wheels toward the curb so a runaway car catches the curb. Facing uphill with a curb, turn the wheels away from the curb so a runaway car rolls into the curb backwards. Without a curb, always turn wheels toward the side of the road. Memorize the visual, not the words.
