While speed limits in Quebec are posted on the side of the road, there are standard guidelines offered to motorists. In general, on highways motorists are advised to keep speeds between 60 km/h and 100 km/h. In business or residential areas, speeds should not exceed 50 km/h.
Like in America, drivers in Quebec drive on the right side of the road. There's an official prohibition against operating a motor vehicle with the driver on the right-hand side.
The minimum driving age in Quebec is 16. Travelers through the province can use their native license for a period of up to 6 months, at which point they'll have to pass the provincial drivers' examination to receive a Quebec license.
Seatbelt use is mandated at all times, by all passengers. Violators are subject to a fine of $100, although many times a warning is issued for first-time offenders. Seatbelt violations can also be tacked on if a driver is pulled over for another offense.
Mobile phones can only be used with a hands-free device. Drivers caught using a mobile phone while driving are subject to fines, typically around $100. It's one of only two provinces in Canada that has such a law on the books, so make sure you turn the phone off when entering the province on a cross-country trip.
Proof of insurance must be carried in the vehicle at all times. All automobile insurance in Quebec is sold via third-party companies; the government offers no official option. However, the government assumes all injury liability resulting from a crash, so drivers need not carry personal liability insurance.
