What to do if…
your windscreen washer jets stop spraying and you have pulled over safely to reassess visibility
Short answer
Don’t continue until you can see clearly through the windscreen. If you can’t restore safe visibility quickly (or conditions are worsening), arrange assistance rather than “pushing on”.
Do not do these things
- Don’t drive “just to the next junction” if the windscreen is smeared/dirty enough that you’re guessing at hazards.
- Don’t keep running the wipers on a dry or gritty screen — it can rapidly worsen the smear and scratch the glass.
- Don’t stop in a live lane to troubleshoot, and don’t stand near traffic to check jets.
- Don’t leave the vehicle on a motorway shoulder/emergency area unless it’s clearly safe to do so from the left side and you can get well away from traffic.
- Don’t put a warning triangle out on a motorway.
- Don’t top up with plain water in freezing conditions if you can avoid it (it can freeze in the bottle/lines and make things worse).
What to do now
- Re-check you’re safe where you are (especially on motorways).
- Hazard lights on; if it’s dark or visibility is poor, use sidelights too.
- If you’re on a motorway hard shoulder or emergency area: if it’s safe to exit, get everyone out via the left-hand doors and wait behind a safety barrier (well away from the vehicle).
- If you cannot exit safely (or there’s no safe place to go): stay in the vehicle, keep your seat belt on, hazards on, and call 999 if you’re in danger/feel at risk from traffic.
- Decide if it’s already “not safe to continue”. Look through the driver’s swept area of the windscreen. If you can’t clearly judge lane lines, vehicles, signs, and pedestrians (or glare is making it worse), treat it as not safe and plan to get help rather than continue.
- Stop the situation getting worse from inside the car.
- Run the demister/defogger (A/C on if available) to prevent mist and grime combining into a film.
- If you have it, use a clean cloth to wipe the inside of the windscreen where fog film builds up.
- Check the simplest cause (washer fluid) if you can do so safely.
- If you’re somewhere safe to access it (for example, off the motorway in a car park/services), check the washer bottle level. If it’s low/empty and you have proper screenwash, top it up.
- Do a quick “pump vs blockage” check. Briefly activate the washers and listen:
- Pump sound but no spray → likely blocked/frozen/disconnected line/nozzle.
- No sound → possible electrical issue (fuse/pump).
- If freezing is likely, treat it as a “get help” problem.
- If temperatures are near/below freezing and you suspect frozen fluid/lines/jets, don’t keep cycling the washers. Keep the cabin warm/defrosting and plan to get assistance rather than attempting roadside fixes.
- If you can safely try a gentle unblock (only in a safe place).
- Wipe grime from the nozzle area. If a nozzle opening looks clogged, a very gentle poke with something fine can sometimes help — stop if it feels like you might damage the nozzle.
- If you cannot restore safe visibility, get assistance instead of continuing.
- Call your breakdown provider.
- If you’re in a motorway emergency area, use the emergency roadside telephone and follow the operator’s advice before attempting to rejoin traffic.
- If you feel unsafe/in danger, call 999.
What can wait
- You don’t need to diagnose whether it’s the pump, fuse, a split hose, or a blocked filter right now.
- You don’t need to decide about repairs, costs, or whether it’s an MOT issue while you’re still roadside.
- You don’t need to clean the whole car or fully flush the washer system now — the only priority is safe visibility.
Important reassurance
This is a common, fixable fault — the risky part is that it can suddenly affect what you can see. Pulling over to reassess was the right move.
Scope note
These are first steps to stabilise the situation and avoid a visibility-related crash. Once you’re safe (home/garage), you can investigate the underlying fault (fluid type, freezing, blocked jets, pump, fuse, hose leak).
Important note
This is general safety information, not mechanical or legal advice. If you cannot maintain a clear view of the road, do not continue driving — get help.
