Driving in Canada for US Visitors (Rules, Insurance, Speed Limits)

Driving in Canada is mostly the same as driving in the US — right side of the road, similar signage, similar etiquette. But there are a handful of differences that catch US drivers out: the speed limits are in kilometres, fuel is in litres, and Quebec specifically bans right turns on red. This guide covers the things US visitors should know before crossing the border with their own car.

The 30-second answer

• License: Your US driver's license is valid in Canada for the length of your visit (60-90 days depending on province).
• Insurance: Most US auto policies extend to Canada automatically — verify with your insurer and ask for a Canadian Non-Resident Inter-Province Insurance Card (free).
• Speed limits: In km/h. 100 km/h on most highways (~62 mph), 50 km/h in cities (~31 mph).
• Fuel: Sold by the litre in Canadian dollars. Most US credit cards work; some Canadian pumps reject US cards without a postal-code prompt — use the cashier inside if so.
• Right on red: Allowed everywhere in Canada except the island of Montreal.
• Insurance proof: Bring your insurance card + rental agreement (if rented). Police regularly do roadside document checks.

Your US driver's license in Canada

A valid US driver's license lets you drive in any Canadian province for the duration of a typical visit:

• Ontario: 60 days.
• British Columbia: 90 days, or 6 months for visitors.
• Alberta: 90 days.
• Quebec: 6 months for non-residents.
• Most other provinces: 60-90 days.

Past those limits, you'd need a provincial Canadian license. For any normal tourist or business visit, your US license is fine.

No International Driving Permit is required for US licenses in Canada. (Some other countries' visitors do need one — IDPs are issued by AAA and similar.)

Insurance

Most US auto insurance policies extend to Canada automatically — the liability, collision, and comprehensive coverages apply at full policy limits while you're temporarily in Canada. Two things to verify before you cross:

1. Call your insurer to confirm coverage. Most policies extend, but the wording varies. The call takes 5 minutes.
2. Ask for a Canadian Non-Resident Inter-Province Motor Vehicle Liability Insurance Card (often called the "Yellow Card" or just "Canadian insurance card"). It's free, your insurer issues it on request, and it's the form Canadian police expect at a traffic stop. Your US insurance card is usually accepted as a fallback, but the Yellow Card removes ambiguity.

Both cards should live in your glovebox alongside your driver's license and rental agreement (if applicable).

Metric — speeds, distances, fuel

Canada is entirely metric on roads. Quick conversions:

Distance signs are also in kilometres. "Toronto 200 km" means about 125 miles. Your car's speedometer probably has a small km/h scale — use it.

Fuel is sold by the litre. 1 US gallon = 3.785 litres. So a price of "$1.50/L" is roughly the equivalent of $5.68 USD per US gallon. Canadian gas is usually more expensive than US gas, though the gap has narrowed in recent years.

Key rules of the road

Right on red

Allowed everywhere in Canada with one major exception: the island of Montreal (the city's central borough). Right turns on red are completely prohibited there — it's posted at the border. Off-island Montreal suburbs allow it normally. The rest of Quebec is fine.

Seatbelts

Mandatory for all occupants, all seats, all provinces. Fines for unbelted passengers in most provinces are $100-300 per person.

Cell phones

Hand-held phone use while driving is banned in every Canadian province. Hands-free (Bluetooth, dash-mounted GPS) is OK in most provinces but check local rules. Fines are steep — often $400-1000 for a first offense — and significantly higher than typical US fines.

Daytime running lights

Required by Canadian law on all vehicles manufactured after 1990. Your US car likely already has them. If you have an older car without DRLs, you're technically supposed to drive with low beams on at all times in Canada — though this is rarely enforced for short-term visitors.

Winter tires

Quebec mandates winter tires on all passenger vehicles from December 1 through March 15. Police enforce this and rental companies provide them automatically. Other provinces recommend but don't mandate them.

British Columbia requires winter tires (or chains) on certain highways October 1 through April 30 — signed at the entrances.

Alcohol

Canada's blood alcohol limit is 0.08% (same as most US states), but several provinces also enforce administrative penalties starting at 0.05%. Penalties for DUI in Canada are severe — and a DUI conviction can affect your ability to enter Canada in future visits.

Reading Canadian road signs

Mostly identical to US signs with metric numbers. Some quirks:

• "Arrêt" on stop signs in Quebec (with or without the English "STOP"). Same meaning, same shape.
• Highway numbering: Provincial highways use their own numbering. The Trans-Canada Highway is signed as "1" most places but follows different routes. Use GPS.
• Pedestrian crossings: Often unmarked at minor intersections. Drivers expected to yield.

Toll roads

Most Canadian highways are free. The notable exceptions:

• Highway 407 ETR in Ontario — an electronic toll road bypassing Toronto. No toll booths; cameras photograph license plates and bill the registered owner. Rental car tolls get forwarded to you with an admin fee weeks later. As a US visitor, you can either avoid the 407 (use 401 or 400) or set up an out-of-province account in advance.
• Confederation Bridge to PEI — fixed toll westbound only (returning to PEI is free). Around $50 CAD.
• Various smaller bridges in Quebec and the Maritimes have modest tolls.

Emergencies

911 works everywhere in Canada, same as the US. The provincial highway patrol equivalents:

• RCMP in most provinces.
• Ontario Provincial Police (OPP) in Ontario.
• Sûreté du Québec in Quebec.
• City police in major urban areas.

All accept 911 calls and dispatch.

Practical tips

1. Get cash in CAD before you go, or use a no-FX-fee credit card. Most places accept both currencies near the border, but exchange rates at small businesses are typically poor.
2. Your phone's GPS works fine but check your roaming plan or buy a Canadian eSIM. Some US carriers offer bundled Canada roaming; others charge $10+/day.
3. Don't leave valuables visible in the car at tourist areas. Vancouver and Toronto have above-average car break-in rates.
4. If you're driving back to the US, check the current wait at your crossing before you leave. Sunday afternoon southbound from BC, Quebec, or Ontario can stretch to 2+ hours.

Bottom line

Driving in Canada is easy. The differences from the US — metric speeds, the Montreal right-on-red rule, the requirement for Canadian insurance documentation — are minor and easy to prepare for. Get your insurer to issue a Canadian insurance card before you leave, brush up on the km/h-to-mph conversion, and time your return crossing to avoid the worst of the queue.
