Common Causes of Motorcycle Accidents in Singapore

Motorcyclists make up a disproportionate share of road fatalities in Singapore each year. Their smaller size, faster acceleration, and vulnerability to weather make them especially prone to accidents on expressways and in urban traffic.

1. Lane Splitting Gone Wrong

Many riders weave between cars in slow-moving traffic to save time, especially along the PIE and AYE during peak hours. This becomes dangerous when a car suddenly changes lanes without noticing the motorcycle beside it.

Prevention tip: Riders should only filter through traffic at low speeds and stay alert to indicator signals from cars. Car drivers, in turn, should do a shoulder check before shifting lanes, since mirrors alone often miss motorcycles in blind spots.

2. Riding Too Close to Heavy Vehicles

Trucks and buses have large blind spots, particularly on the sides and directly behind them. Motorcyclists who linger in these zones risk being unseen by the driver, especially when the heavy vehicle turns or changes lanes.

Prevention tip: Avoid riding alongside trucks and buses for extended periods. If overtaking, do so quickly and decisively rather than cruising next to the vehicle.

3. Wet Weather and Reduced Traction

Motorcycles are far more affected by rain than cars, since two wheels offer less grip than four. Painted road markings and metal grates become especially slippery when wet, and this catches many riders off guard.

Prevention tip: Reduce speed significantly in the rain and avoid sudden braking or turning on painted lines, metal drain covers, and expressway joints. Wearing proper riding gear also reduces injury severity if a fall does occur.

4. Fatigue on Long Rides

Riders travelling long stretches, such as commuting from Woodlands to the city or doing food delivery runs across the island, often underestimate how tiring riding can be compared to driving a car.

Prevention tip: Take short breaks every hour or so during long rides. Recognise early signs of fatigue like drifting concentration or slower reaction times, and pull over rather than pushing through.

5. Poor Visibility at Night

Motorcycles have a smaller visual footprint than cars, making them harder for other drivers to spot at night, particularly at junctions and when emerging from side roads.

Prevention tip: Use reflective gear and ensure headlights and taillights are functioning properly. Avoid riding in a vehicle’s blind spot, and position yourself where your headlight is visible in the mirrors of the car ahead.

Final Thoughts

Motorcyclists face risks that car drivers often don’t fully appreciate, and vice versa. Mutual awareness between both groups, especially around blind spots and lane discipline, is one of the most effective ways to bring these numbers down.
