Because motorcycles are so much narrower than cars, they can sit entirely within another vehicle's blind spot, or blend into a cluttered background, in a way a full-sized car rarely does. This is why defensive riding places such emphasis on positioning — riders are taught to avoid lingering in other vehicles' blind spots, to use lane position to maximise their visibility to drivers ahead, and to assume other road users simply haven't seen them until proven otherwise. Bright or reflective riding gear, and a headlight left on even during the day, both meaningfully improve how easily a rider is noticed. None of this replaces other drivers' responsibility to check properly, but riders who actively manage their own visibility measurably reduce their risk.

Frequently Asked Questions
Why are motorcycles harder for drivers to see than cars?
Their narrow profile means they can fit entirely within a blind spot or blend into background clutter far more easily than a full-sized vehicle.
Does riding gear colour actually make a difference?
Bright or reflective gear improves contrast against the road environment, making a rider meaningfully easier for other drivers to notice.
Should motorcyclists ride with headlights on during the day?
Many riders and safety programmes recommend it, since a lit headlight improves visibility to oncoming and crossing traffic even in daylight.
What's the safest assumption for a motorcyclist to make about other drivers?
That other drivers may not have seen them at all, which encourages proactive positioning and readiness to react, rather than assuming right of way will be respected.
