Observation, mirror and blind-spot checks, signalling
Systematic observation
Observation is marked continuously, not only at junctions. Mirror checks should be frequent enough to keep a picture of traffic behind, roughly every five to eight seconds on the move, and always before signalling, braking, changing lane, overtaking or opening a door. A mirror alone is not enough: the blind spot beside the rear quarter must be checked with a quick shoulder glance before moving off, changing lane or reversing.
Signalling
Signal early enough to inform, but not so early that it misleads. Cancel after the manoeuvre; a signal left on tells other drivers you intend to turn and can cause them to pull out. Use indicators for lane changes, turns, roundabout exits and parking. In Jordan, hand signals are still useful if an indicator fails, so know the basic arm signals.
Worked example
You intend to change lane on a three-lane urban road. Check the interior mirror, then the side mirror on the target side; if a car is closing, wait. Signal, check the blind spot with a shoulder glance, and move only when the lane is clear. If a vehicle appears in the blind spot after you signal, cancel and wait; signalling does not give you priority. The reasoning is that the mirror leaves a gap that the shoulder check covers.
Traps that cost marks
Signalling after the manoeuvre; leaving the indicator on; checking the mirror but not the blind spot; braking before checking behind; and signalling a turn you do not take.
