Alertness

Last reviewed against gov.uk on

Alertness covers everything that keeps a driver in tune with what is happening around the vehicle — using mirrors before signals and manoeuvres, judging hazards before they unfold, recognising fatigue, and resisting distractions like phones and in-car tech.

What’s tested

  • Effective use of mirrors — what they show and when to check them
  • The mirrors-signal-manoeuvre (MSM) routine
  • The “lifesaver” shoulder check before changing direction
  • Recognising and responding to fatigue on long or familiar routes
  • Avoiding distractions: handheld phones, eating, conversations

  • Underestimating tiredness on motorways or familiar routes
  • Using a handheld phone for navigation (illegal — and a points-and-fine offence)
  • Skipping the final shoulder check before pulling out from the kerb
