This is a question that we are frequently asked at Fantoni driving school.In this blog we will answer that question for you.On the DL25 marking form that Driving examiners use, there are 3 main categories of driver fault.The three main categories of fault on the driving test are:-Driver fault.A driver fault or, “minor” could be explained as an omission in driving procedure that carries a small risk of danger to the driver and other road users. A single one of these  wouldn’t be enough on its own to fail a driving test. However, if these omissions were carried out repeatedly, this could result in a more serious risk.An example would be if the driving test candidate forgets to check their, “blind spot” before moving off. If this same fault happened repeatedly during the test, this could then be deemed to be a “serious” fault.Serious/“Major” Fault.This is a driving fault which carries a greater level of potential risk. One of these would result in a driving test fail.An example would be when someone badly cuts the corner when turning right into a side road. There would be a serious risk of colliding with an oncoming that could be emerging from the side road.This level of risk would be regarded as an unacceptable level of risk. A single serious fault would also therefore result in a driving test fail.Dangerous fault.This type of fault would also be regarded as a “major”fault. This is where a high level of danger has actually occurred on the driving test. An example would be when the driving test candidate has turned right into a side road, forcing an oncoming car to stop. The oncoming car has priority in this situation. A driving behaviour such as this would be highly likely to result in a serious crash in the foreseeable future. This level of risk would also be classed as beyond acceptable, and would result in a driving test fail.This explanation as to what makes a “major” or “minor” fault  has been fairly brief. However, it should  still help you with you understanding of the driving test marking scheme.
