Safe and defensive riding technique for mopeds and light quadricycles
Safe and defensive riding technique covers how you control a moped or light quadricycle in real traffic: road position, braking, cornering, following distance, and surfaces that give a two-wheeler far less grip than a car has.
Road position and control
- Ride in the right third of the lane, but about a metre out from parked cars (the door zone) and out of the gutter, where debris and drains collect. Slightly left of the edge keeps you visible.
- Braking: both brakes together, front progressively harder - the front wheel carries most of the weight and gives most stopping power. Snatching the front lever locks the wheel and puts you down.
- Cornering: slow before, look through the bend, accelerate gently out. Do not brake hard while leaned.
- Following distance: at least 2 seconds dry, 4 seconds wet, and more than that behind trucks, at night, or with a passenger.
- Slippery surfaces: painted markings, tram rails, manholes, gravel, wet leaves. Cross them upright with steady throttle.
- Light quadricycle: belts for every occupant; its narrow track and higher centre of gravity mean braking and cornering earlier. Its 45 km/h is a maximum, not a target.
Worked example
You ride at 45 km/h (12.5 m/s) on a wet road and a car pulls out 30 m ahead. Reaction of one second takes 12.5 m; braking at roughly 3 m/s² needs another 26 m - about 39 m, so the crash happens anyway. The lesson is not better braking but better positioning: cover the brakes near junctions, drop speed, and always keep an escape line.
Traps that cost marks
Using only the rear brake, braking mid-corner, riding so close to the kerb that parked cars hide you, and swerving while hard on the brakes - choose brake or swerve, not both.
