Quad bikes are classified as all-terrain vehicles (ATVs) and are designed for off-road use. They are not considered to be safe for use on public roads, particularly high-speed roads like motorways, due to their lack of stability, low ground clearance, and inadequate safety features.
Additionally, quad bikes are generally not equipped with the necessary lighting and signalling devices required for road use, which makes them difficult to see and can pose a safety hazard to other road users.
For these reasons, it is illegal to ride a quad bike on a motorway in most jurisdictions.
