In plain English
Stripped of the formal wording, Rule 93 comes down to one idea: rule 93 (Fitness to drive (rules 90 to 94)) Slow down, and if necessary stop, if you are dazzled by bright sunlight. It is advice rather than law, but examiners and the courts still treat it as the expected standard of safe driving.
It belongs to the rules for drivers and motorcyclists part of the Code, the habits a confident, considerate driver builds until they are automatic. The aim is not to memorise the sentence word for word, but to understand the hazard it protects you from, so you apply it without having to think when it counts.
If you are learning, treat this rule as one piece of a connected set rather than an isolated fact. The related rules below sit in the same section and reinforce each other, reading them together is how the rules for drivers and motorcyclists part of the Code starts to feel like common sense rather than a list to revise.
Because this is advisory rather than legal, no one will fine you for the rule alone, but ignoring it can still count against you in a careless-driving case, and it will cost you faults on the test. Either way, the safe move is to build the habit early, while a driving instructor can correct it, rather than relearning it under test pressure. That is exactly what the practice routes and coaching in the DriveRoutes app are designed to help with, turning the rules below into the way you naturally drive.
Why rule 93 matters on the road
Pedestrians, cyclists, motorcyclists and horse riders have little protection in a collision, so a moment of inattention from a driver can cause serious harm. Anticipating and giving them room is one of the clearest signs of a safe, considerate driver.
Common faults examiners record
In the rules for drivers and motorcyclists part of the Code, the faults most often written on the marking sheet tend to be the same handful. Knowing them in advance is the quickest way to drive them out of your own habits:
- Passing cyclists or horses too closely or too fast.
- Failing to anticipate a pedestrian stepping out near a crossing or parked cars.
- Not giving way at a crossing when someone is clearly waiting.
On the day
Imagine approaching a cyclist on a narrow stretch during the drive. Applying Rule 93 means easing off early, holding back until you can see it is genuinely safe, then passing wide and slow before returning to your line. The examiner is watching for exactly that anticipation, not a squeeze past at speed.
Quick checklist
- Scan ahead for pedestrians, cyclists and riders well before you reach them.
- Give them room and time, pass wide and slow.
- Be ready to stop at crossings and side roads.

Rule 93, your questions
Rule 93 (Fitness to drive (rules 90 to 94)) Slow down, and if necessary stop, if you are dazzled by bright sunlight. It is advisory guidance rather than law, but you are still expected to follow it and an examiner can mark a fault if you do not.
