Impaired Driving & Penalties — Ontario

An M1 rider's blood alcohol level must be zero — no alcohol at all before riding. The handbook's Level One section lists the M1 conditions directly: you must not ride after drinking, and your blood-alcohol level must be zero. That is a stricter rule than the general limit that applies to fully licensed drivers, so for an M1 holder any alcohol in the blood is over the line. The passage spells the requirement out plainly, which is why the zero figure is the one to remember.

Any of the above can affect your ability to ride a motorcycle: illegal drugs, prescription medications and over-the-counter medications. The handbook says that apart from alcohol, almost any drug can make it unsafe to ride. It names illegal drugs and prescription drugs, and it adds non-prescription products such as cold tablets or allergy pills. Those can make a rider weak, dizzy or drowsy. Because the warning covers all these kinds of drugs, it is not limited to one category; illegal, prescription and over-the-counter medications can all affect your riding.

Alcohol can impair a rider's ability to turn at night, stop and control the motorcycle, so the correct choice is All of the above. The night-riding passage says alcohol reduces your ability to control your vehicle and to anticipate trouble from others. The alcohol section adds that balance, steering, speed control and distance perception may be off, and that judgement can be clouded. Turning, stopping and general control all depend on those same skills, so the handbook's warning covers each ability named in the choices.

Roads and weather conditions affect motorcycle riders more than four-wheel vehicle drivers. The handbook tells riders to leave more space when weather is bad and to watch for sudden road surface changes, icy patches and black ice in cold weather. It also says other drivers may not expect motorcycles in winter, so riders must be more careful. Those motorcycle-specific warnings make roads and weather the choice that fits the passages.
