Driving licence practice tests

Alberta's Class 7 knowledge test is 30 questions, and it stops the moment you've got 25 right or 6 wrong. These sets build up to that.

The G1 knowledge test is commonly delivered as two 20-question sections - road signs and rules of the road. We practise them separately so a strong half can't hide a weak one.

A flashing green light means the opposite here to what it means in Alberta, Ontario and the Maritimes - and that single sign catches more drivers moving to BC than anything else in the guide.

Texas passes at 70% - the most forgiving mark in the US - but the questions still come straight out of the handbook.

Florida asks 50 questions and wants 40 right. The insurance rules catch people out - it is a no-fault state, so the minimums it tests are not the ones most drivers expect.

New York has a second hurdle most people miss: 14 of 20 passes, but miss three of the four road-sign questions and you fail anyway.

Pennsylvania asks only 18 questions but wants 15 right, so there is almost no room to guess - one of the tightest margins anywhere.

Ohio asks 40 questions and passes at 75%. Watch the probationary night hours - they change after your first year, not on your birthday.

Georgia scores road signs and road rules as two separate exams of 20, and you need 15 in each. Ace the rules and fluff the signs and you still fail.

Scott's Law is the single most-missed topic in Illinois, and the penalties are far heavier than people expect. These sets lean into it.

North Carolina runs the signs test as a separate exam, and several of its rules are the opposite of what drivers from other states expect - the horn before overtaking, two feet of passing clearance, two seconds of following distance.

Michigan runs the test as two separately-scored parts - operator rules and signs - and you have to clear both. Pass one and fail the other and you retake the whole thing.

New Jersey has more genuinely unusual rules than any other state here - it legislates for ice cream trucks, sets the curfew at 11:01pm, and declines to state a priority rule for traffic circles at all.

Virginia gates the whole exam behind signs: all ten sign questions must be right before the 30-question second part even opens. Miss one and you are done for the day.

California leans hard on parking rules - coloured curbs and which way your wheels point on a hill show up far more than people expect.

Washington's guide is unusually plain-spoken, which cuts both ways: it states some rules as memory aids rather than law, and it leaves out numbers the test still asks for.

The shortest exam on this site, and the least forgiving: 25 questions in 25 minutes, and a Junior Operator licence that punishes a single speeding ticket harder than most states punish three.

Tennessee is the rare state that tells you the syllabus but not the score: the manual publishes an exact topic split and no question count at all.

Arizona teaches two things no other manual does, and both run opposite to instinct: in a dust storm you turn your lights off, and driving around a flood barricade makes you pay for your own rescue.

Indiana words its tie-break backwards from everywhere else: at an all-way stop it is the vehicle on the LEFT that yields. Then at a dark signal it flips back.

The Missouri Driver Guide tells you something no other state prints: almost half of everyone who sits this test fails it the first time.

The strictest pass mark on this site: 88%, which on a 25-question test means you may get three wrong and no more.
