As a car driver for forty seven years, a motorcyclist for twenty three years and an LGV C+E (HGV Class 1) for twenty years and having a wife who passed her test some ten years ago I feel I am well-placed to comment on the driving test; it's not tough enough by far.
The theory test is a joke and only an imbecile should fail it. Before I am attacked from all sides allow me to post a couple of sample questions taken from the DVLA website:
1) You are driving on a motorway. You have to slow down quickly due to a hazard. You should:
a Switch on your hazard lights
b Sound your horn
c Switch on your headlights
d Flash your headlights
2) You are driving behind a large goods vehicle. It signals left but steers to the right. You should:
a slow down and let the vehicle turn
b overtake on the right of it
c drive on, keeping to the left
d hold your speed and sound your horn
Surely no one needs to even look up the answers because if the taker of the exam can't work out the correct answer to these two questions then I put it to you that they shouldn't be leaving the house, let alone driving a lethal weapon at national speeds. (For those people, the answers are both 'a').
The actual test has been shortened in as much as the candidate need only carry out one of the three basic manouvers instead of all three as was the case in times gone by. The test is forty minutes long but the actual driving is only thirty minutes which has not changed for many years.
The extended test which previously disqualified drivers may need to take is seventy minutes long and I put it to you that this should be the baseline test time for all new drivers. In addition, as has been mentioned by others, no passengers for at least a year after passing a test to avoid the 'showing off' phase of a new driver, A 'P' plate to be displayed for a year with a speed limit of 50 miles per hour during that year and no access to motorways for at least six months after passing the test.
Driving conditions these days are much trickier than they were when I first passed and I have seen them change through my two subsequent tests, plus I have had driving assessments as part of my employment so I have seen how things have become more difficult over time.
I would quite happily retake my theory and practical test every, say, ten years. Not going to happen though and under twenty-fives will continue to be the bane of responsible people's lives because they have a new toy and want to show it off to their mates...and people will die because of it.
