Grade 1, 2, and 3 Driving Faults Explained
Understand how the Irish driving test is marked, the difference between Grade 1, 2, and 3 faults, and how many mistakes you can make.
Grade 1 Faults (Minor)
These are minor mistakes that do not affect safety. For example, a slight hesitation or a clumsy but safe gear change. They are recorded but do not cause you to fail, no matter how many you get.
Grade 2 Faults (More Serious)
These are potentially dangerous faults. For example, poor observation, incorrect road position, or failing to check mirrors. If you accumulate too many Grade 2 faults, you will fail the test.
Grade 3 Faults (Dangerous)
A Grade 3 fault is a dangerous or potentially dangerous error that requires the tester to intervene, or poses an immediate risk to other road users. A single Grade 3 fault results in an automatic fail.
Quick Answers
How many Grade 2 faults are allowed on the Irish driving test?
You will fail if you accumulate 9 or more Grade 2 faults overall, or 4 or more for the exact same error, or 6 or more under the same general heading. If you keep your Grade 2s to 8 or fewer and spread them out, you can pass.
What happens if I get a Grade 3 fault?
A single Grade 3 fault is a direct fail. It means the examiner deemed the action dangerous to yourself, the examiner, or other road users.
Does a stalled engine mean I fail the driving test?
Not necessarily. If you stall the car but recover safely, secure the car, check your mirrors, and restart calmly, it may only be a Grade 1 or Grade 2 fault. It only becomes a fail if it causes danger to others or happens repeatedly.
