Manitoba's Trans-Canada Highway stretches across some of the most sparsely populated terrain in Canada. It's stunning country — but it's also not the place to have a breakdown that a 30-minute inspection could have prevented.
Many drivers skip pre-trip vehicle checks and end up stranded hundreds of kilometres from a service station, turning a weekend getaway into a long and expensive ordeal. Whether you're heading from Winnipeg to Portage la Prairie, Brandon, Riding Mountain National Park, or beyond, this checklist covers everything you need to inspect before departure. Need roadside help while travelling? Jets Towing covers the Winnipeg area 24/7 — call (431) 791-1122.
The Pre-Trip Mechanical Checklist
A thorough mechanical check before a long Manitoba drive takes under an hour. These are the systems most likely to fail on a highway run:
Oil and Fluids: What to Check Before Departure
- Engine oil: Check the level and condition. If you're within 2,000 km of your next oil change, do it before the trip — highway driving generates sustained heat that accelerates oil breakdown.
- Coolant: Check the reservoir level. Low coolant is a leading cause of highway overheating. Inspect visually for any leaks under the car after it's been parked overnight.
- Brake fluid: Should be at the MAX line. Unusually low levels can indicate a slow leak.
- Power steering fluid: A minor check, but a steering issue at highway speed is dangerous.
- Windshield washer fluid: Essential for summer driving — Manitoba highways produce significant bug splatter and road spray that can reduce visibility quickly.
Tires: Pressure, Tread, and Spare
- Tire pressure: Inflate to the manufacturer's spec found on the sticker inside the driver's door jamb — not the maximum PSI on the tire sidewall. Incorrect pressure causes uneven wear and affects fuel economy on long drives.
- Tread depth: Insert a quarter into the tread groove. If you can see the top of the caribou's nose, the tread is low — replace before a long trip.
- Spare tire: Check that it's properly inflated. A flat spare is useless on the side of PTH 1. Confirm the jack and lug wrench are in the vehicle.
- Brakes: If you hear squeaking or feel a pulsing in the pedal, have brakes inspected before the trip — not after.
Some Manitoba highway stretches have gas stations 80+ kilometres apart. Always keep your fuel above a quarter tank on remote routes.
Electrical and Comfort Systems
Electrical failures are annoying in the city and genuinely problematic on a remote Manitoba highway.
- Battery: If your battery is more than 3 years old, have it load-tested before a major trip. A battery that barely starts the car at home won't make it 400 km. See our guide on what to do with a dead battery for testing details.
- All lights: Walk around the car with someone pressing the brake pedal. Check headlights, taillights, brake lights, and turn signals. A burned-out brake light on a Manitoba highway is a genuine rear-end collision risk.
- Air conditioning: Manitoba summers regularly reach 35°C. A failing A/C on a long drive is more than uncomfortable — heat fatigue impairs driving ability. Test it before you leave Winnipeg.
- Wiper blades: Summer thunderstorms in Manitoba can be intense. Worn wiper blades that smear rather than clear create dangerous visibility gaps. Replace if they streak.
What to Pack in Your Road Trip Emergency Kit
The right emergency kit shifts from a nice-to-have to a genuine safety necessity once you're on Manitoba's remote highway corridors. Pack these before you leave:
- Jumper cables (at least 4 metres, 16-gauge) or a portable jump pack
- Reflective triangle or LED road flares
- First aid kit: bandages, antiseptic, pain relievers, personal medications
- Extra water — at least 2 litres per person
- Non-perishable snacks: granola bars, nuts
- Blanket (even in summer — nights in Manitoba can be cold)
- Flashlight with fresh batteries
- Phone charger cable and portable power bank
- Pen and paper for insurance information exchanges
Cell Coverage Dead Zones on Manitoba Highways
Cell coverage drops significantly outside Winnipeg and major centres. Stretches of the Trans-Canada, PTH 16, and northern routes can have minimal or no service for extended distances. This affects not only your ability to call for help but also navigation apps that depend on live data.
Why Paper Maps Still Matter
Download offline maps before you leave — Google Maps and Apple Maps both support this. But also keep a paper map of Manitoba in the glovebox. If your phone dies and the power bank is dead too, a paper map is the only fallback. They're available for free at most Manitoba visitor information centres and many gas stations.

Call (431) 791-1122Planning Your Route and Service Stop Strategy
Route planning for a Manitoba road trip is different from planning a drive in southern Ontario. There are fewer services, longer gaps between towns, and more potential for complete cell outage in an emergency.
- Know your fuel gaps: Before leaving, map the gas stations on your specific route. Some Manitoba stretches are 80+ km between stations. Never let the tank drop below a quarter on remote corridors.
- Plan rest stops every 2 hours: Driver fatigue is one of the leading causes of highway accidents in Manitoba. Build in stops at Portage la Prairie, Carberry, or other centres on your route.
- Download Manitoba 511: The province's highway conditions app provides real-time road status, construction delays, and weather alerts. Particularly useful in spring (flooding) and fall (early snowfall).
- Know who to call: For roadside emergencies departing from Winnipeg, fuel delivery and other roadside services are available through Jets Towing. Save the number before you go.
A thorough pre-trip check takes under an hour and prevents the kind of breakdowns that ruin trips and cost hundreds or thousands to resolve on the roadside. Manitoba's highways are beautiful — preparation is what lets you enjoy them without incident.

Frequently Asked Questions
How do I prepare my car for a long Manitoba road trip?
Check oil and coolant levels, inspect tire pressure and tread, verify your spare tire is inflated, test your battery if it's over 3 years old, check all lights, and ensure your A/C and wiper blades are working. Pack an emergency kit with jumper cables, a flashlight, first aid supplies, water, and a portable charger.
Are there cell coverage dead zones on Manitoba highways?
Yes. Coverage drops significantly outside Winnipeg and major centres. Stretches of the Trans-Canada, PTH 16, and northern routes can have minimal or no signal. Download offline maps and carry a paper map as backup.
How far apart are gas stations on Manitoba highways?
On some routes, gas stations can be 80 kilometres or more apart. Keep your fuel above a quarter tank when driving remote Manitoba corridors and fill up whenever you pass a service station.
What should I do if I break down on a Manitoba highway?
Pull off the road safely, turn on hazard lights, and stay with your vehicle. Call Jets Towing at (431) 791-1122 for Winnipeg-area coverage. Download Manitoba 511 before your trip for real-time road conditions.
