Being seen is not the same as being noticed
Most drivers and pedestrians are not trying to cause problems. Many collisions between bikes and other road users happen because the other person simply did not register the cyclist: they looked but did not notice, they were thinking about something else, or they expected a gap that was not there. A bike is narrow and quiet, and it can be easy to overlook beside larger vehicles.
Anticipating others means assuming that you might not have been seen, and giving yourself enough room and time to cope if that is true. It is not about blaming anyone. Rules about who should give way differ by country and junction, so check the local rules, and remember that being in the right is little comfort if you are hurt.
Turning vehicles
Turning vehicles are one of the most commonly discussed risks for cyclists. A driver turning across your path may be watching for gaps in oncoming traffic and not for a rider on the side. A driver turning in the same direction as you may not realise you are beside the vehicle, particularly with larger vehicles that have blind areas.
Some general principles:
- Be cautious about riding alongside a large vehicle near a junction, especially on its inner side. If a driver cannot see you, they cannot avoid you.
- Watch the front wheels and indicators of vehicles waiting to turn. Wheels often turn before the vehicle moves.
- Try to make eye contact, but do not rely on it. A look from a driver does not guarantee they have seen you, and does not guarantee what they will do next.
- If you are unsure, slow down or wait. Giving way when you did not need to costs a few seconds.
Large town junctions with several lanes add their own demands, which is why busy junctions are worth approaching slowly and early.
Doors and parked vehicles
People opening car doors without checking is a well-known hazard, and the safest approach is usually to keep clear of the area a door could swing into. Watch for signs that someone is in a parked car: brake lights, exhaust, a figure in the seat, or a vehicle that has just pulled up. Ride-share and taxi stops deserve extra care because people often get out quickly.
Vehicles pulling out from parking spaces or driveways are a similar risk. A car edging forward slowly may not have seen you. The detailed approach to positioning near parked cars is a separate topic, so here the main point is to expect a door or a vehicle to move and to leave space for it.
Side roads and driveways
Drivers emerging from side roads and driveways often look for larger, faster traffic, and a bike can slip through a blind spot behind a pillar or a parked van. Cover the brakes as you pass, scan for vehicles with their engines on or wheels turning, and be ready to slow. A rider on a path beside a road may be even less expected, since drivers may not look in that direction at all.
Pedestrians
People on foot can change direction without warning. Common situations include:
- Someone stepping off a kerb while looking at a phone or at traffic in the other direction.
- Groups spreading across a path.
- Children and dogs, who can move very suddenly, particularly if a dog is on a long lead.
- People stepping out from behind parked vehicles or buses.
- Walkers with headphones who cannot hear you approach.
On shared paths in particular, slow down when passing, give plenty of room, and be ready to stop. A bell or a friendly voice helps, though neither guarantees the person will react as you hope. The manners of shared paths and bell use are discussed in shared path etiquette and bike bell use.
Leave space, speed and time
Three things give you room to cope with a mistake by someone else.
- Space. Ride where you have somewhere to go if something happens. Pressing yourself into the gutter often leaves you with no escape.
- Speed. A lower speed gives everyone more time. Slowing as you approach a hazard is often the quickest way to make a situation safer.
- Time. Cover your brakes, keep your hands ready, and avoid being caught in a hurry.
None of this removes risk completely. It shifts the odds in your favour and gives you a better chance to adapt.
Help others notice you
You can’t control what others do, but you can make yourself easier to see. Riding in a clear and consistent position, signalling in good time, and using lights and bright or reflective clothing as appropriate all help. Lights are not only for night, and the details of using them are covered in riding with bike lights. Visibility is helpful, but it should never replace caution, because being visible does not guarantee being seen.
Practise the mindset
A simple exercise is to narrate your ride quietly for a few minutes: “car waiting to turn, might not see me; pedestrian near kerb, may step out; door zone ahead, moving out.” Doing this on a quiet street helps the habit stick. Wear a helmet, ride within your comfort level, and build up to busier places gradually.
