Distractions while driving can be considered negligent if they interfere with the driver's ability to control the vehicle.
A Canadian driver who after spilling coffee on his leg while driving, then lost control and ended up wiping out in the ditch. The driver was charged with Careless Driving under Canada’s Highway Traffic Act.
The Canadian law he was charged under appears to be a crime; or like we have a lesser criminal violation that results in a fine. Sort of like speeding. Had he struck another car or wrecked someone's property if he pleads guilty to the ticket charge, it can be used against him as evidence that he admitted to violating the rule of the road. This is what lawyers call an admission against interest.
