Heaviest on Traffic Signs & Signals (8 of 20) — that is the section to revise first if you miss several here.
2 are Hawaii-specific questions, drawn from the state handbook rather than general road rules.
Each test on this site draws a different set, so Test 1, 2 and 3 never repeat a question.
Answer: Faster than the posted max, or slower than the posted min / so slow you hold up traffic
Don't exceed the posted maximum, drop below a posted minimum, or drive so slowly you block traffic.
Answer: 100 feet
Signal at least 100 feet before turning.
Answer: Pedestrians crossing the road you're turning onto
Pedestrians may be crossing the street you turn into — yield to them.
Answer: Reduce your speed for the work zone ahead
Orange reduced-speed signs mean slow down for the upcoming work zone.
Answer: Alcohol, illegal drugs, or even prescription/OTC medicine that impairs you
DUI covers alcohol AND any drug — including prescription or over-the-counter medicine — that impairs driving.
Answer: A winding road — a series of curves ahead
This warns of a winding road (several curves). Reduce speed.
Answer: Signaling early, then checking mirrors and your blind spot
Signal first so others know your intent, then check mirrors and blind spot before moving.
Answer: Slow down — it is a slow-moving vehicle traveling under 25 MPH
The orange triangle marks a slow-moving vehicle (under 25 MPH). Slow down and pass only when safe.
Answer: The road does not go through
These signs mean the road ends or has no through route.
Answer: Regulatory (a law you must obey)
Speed-limit signs are regulatory — the posted limit is the law.
Answer: Treat it as a four-way stop
A dark signal = four-way stop; take turns in the order you arrive.
Answer: Counter-clockwise; yield on entry and signal to exit
Roundabout traffic moves counter-clockwise. Yield to traffic already circulating, then exit when you reach your street.
Answer: A truck crossing or entering the road ahead
A truck-crossing sign warns that trucks may be crossing or entering; watch for them.
Answer: Visual, manual, and cognitive (eyes, hands, mind)
Distraction takes your eyes (visual), hands (manual), or mind (cognitive) off driving — texting does all three.
Answer: Turn after yielding to oncoming traffic and pedestrians
A flashing yellow arrow permits the turn once you yield to oncoming traffic and pedestrians.
Answer: A steep hill where trucks may move slowly
It warns of a steep downgrade; watch for slow-moving trucks.
Answer: Have an escape path if a hazard appears
Side space gives you somewhere to go if a hazard suddenly appears.
Answer: Stop, yield, or prohibition
Red signals stop, yield, or a prohibited action.
Answer: Brake gently and early
Gentle, early braking keeps traction; hard braking causes skids on slick roads.
Answer: Braking hard in a curve can cause a skid
Brake before the curve; braking or accelerating hard mid-curve can break traction.
