Exceeding the speed limit

Going over the posted limit — even briefly — is one of the most common Grade 3 faults on the Irish test.

Crawling well below the limit when it's safe holds up traffic and is marked under 'Progress'.

If the car ahead brakes and you're too close, you can't stop. Keep at least a two-second gap — four in the wet.

Braking suddenly because you didn't plan ahead risks being hit from behind and shows poor anticipation.
