Here's a couple more...
A traffic light is only red if you can see it head-on. If it is above your eye-line it doesn't count.
Indicating to turn should be done simultaneously with the turning of the steering wheel, to prevent other road users from guessing your intentions. If you accidentally signal a turn too early, cancel the signal, flick it the other way momentarily, then back to the first direction again just as you turn off.
When meeting an oncoming vehicle in a narrow country lane, priority is with the black SUV driven by the blonde in Ray-bans, as the combination of shades and 20%-transmission privacy glass means she cannot see to reverse, and couldn't back the car even if she could see, as she always gets hubby to do that for her when he comes back from Canary Wharf in the evening.
Unsilenced exhausts are only illegal if you can hear them above the sound of the stereo.
