Alertness
The Alertness domain tests observation, concentration and your fitness to be behind the wheel. Questions put you in a situation - a junction, a kerbside pull-out, a ringing phone, a long drive home - and ask what you should have checked, when, and in what order. The examiner is testing habits rather than trivia: if you look early and often, most of the other domains look after themselves.
Mirrors, signals and blind spots
The core routine is mirror, signal, manoeuvre, and the order is not optional. Check mirrors before signalling, before changing speed or direction, and before opening a door. Act on what the mirror shows - a glance that changes nothing you do was not a check. The interior mirror gives the first picture of what is behind and how close it is; the door mirrors cover the sides. Neither shows the blind spot over your shoulder, so turn your head before moving off, changing lane or pulling in. Signal in good time so others can react, and cancel it afterwards, because a signal left on tells other drivers something untrue.
Fitness and distraction
Holding a phone while driving is an offence and blinds you for as long as you look at it; a hands-free kit is legal but still takes your mind off the road. Set the sat-nav and music before you move. Tiredness gives little warning: yawning, heavy eyes, drifting and missing signs mean stop somewhere safe and rest - opening a window does not work. Alcohol, drugs and some medicines slow reactions and can still affect you the next morning, so read the label. You must be able to read a number plate at 20 metres; wear your glasses if you need them.
Lights and horn
Flashing your headlights means only one thing: I am here. It does not mean 'go ahead' and it gives nobody priority. Use the horn to warn others you are there when they may not have seen you - never to show annoyance.
Worked example
You are waiting at a T-junction to join a busy road. Mirrors first, to see who is behind you; signal if you are turning; position and slow down. At the line, look both ways, then look again, because a gap you saw a second ago can close while you check the other direction. The second look is what catches the cyclist who appeared while your head was turned. If a parked van blocks your view, edge forward slowly until you can see clearly rather than pulling out and hoping.
Traps that cost marks
- Signalling and assuming you have been seen.
- Braking first and checking the mirror afterwards.
- Watching only the vehicle in front instead of the road beyond it.
- Treating a flashed headlight as an invitation.
