Re: The Highway Code
I tend to hate these kind of pithy tests because they are fraught with ambiguities.
The tyre tread question.
Strict answer 1.6mm yet every expert out there takes it as 3mm because tyre performance and stopping distance are drastically reduced below 3mm. I'm pleased therefore to know the realistic right answer to that one. 3mm.
The question about invalidating your warranty by using an independent garage. Ambiguous. If the local garage fits an incorrect or dodgy part which subsequently damages the engine or other significant component then for sure, the manufacturer isn't going to honour your warranty. Turn up to the main dealer to get the engine fixed and they'll charge you for the costs and you'll be fighting the local garage for the damages. So, a bit of a silly question.
If the work was done at a main dealer and THEY damaged the engine then no question your warranty would be intact and they would pay all costs.
The question about when using a mobile phone is illegal. Ambiguous. It didn't state whether you are driving or not at the time. One of the options was "when on the motorway to call 999 in an emergency". Are they actually saying it's fine to use your mobile phone WHILST DRIVING to call 999? Surely they would expect you to pull over first?!
And like others here I didn't get the lane merging question correct. The reality is people don't merge in turn because the queues are formed way back from where the lane closes and everyone knows people in the right lane are just pushing in. So it will always be. Nonsense question imo.
As ever, the one thing you learn quickly after passing your driving test is that learning the rules to pass the test is one thing, but actually learning the law of the road jungle is an entirely different thing. One has to become streetwise very quickly.
