Michigan Summer Road Trip Breakdown Guide: Before, During, and After

The guide you should read before Memorial Day weekend

Every year, Michigan roads fill up between Memorial Day and Labor Day with road trippers heading to Traverse City, Mackinac Island, the lakeshore, and Up North. And every year, we take calls from people who broke down 30 miles from the nearest town because they didn't check one thing before they left. This guide has three parts: what to do before you leave, what to do if you break down, and what to do after you're safe.

Part 1: Before you leave — the 20-minute pre-trip check

A summer breakdown is almost never random. It's a cooling system that was already marginal, a tire that was already low, or a battery that was already weak. Twenty minutes in your driveway catches most of it.

Tires

Check all four tires plus the spare. Use a gauge — you can't tell tire pressure by looking.

• **Target pressure:** whatever's printed on the sticker inside the driver's door jamb (not the sidewall of the tire — that's the maximum, not the recommended).
• **Penny test for tread:** insert a penny into the tread groove with Lincoln's head pointing down. If you can see the top of his head, the tread is below 2/32" and the tire needs replacement before a highway trip.
• **The spare:** Is it there? Is it inflated? A surprising number of newer cars don't carry a spare — they come with a tire sealant kit instead. Know which yours has before you're on the shoulder of US-31 at sunset.
• **Look for sidewall bulges and cracks.** A bulge means the internal structure is compromised. It can blow out without warning at highway speed.

If a tire needs replacing, do it before the trip. Our [flat tire change](https://primeotowing.com/services/flat-tire-change) service mounts your spare roadside, but there's no roadside fix for a tire that's worn to the cords.

Coolant

Pop the hood and check the coolant overflow reservoir. It should be between the "min" and "max" lines. If it's below minimum, top it off with the correct 50/50 mix. If it's brown, oily, or has particles floating in it, the system needs a flush — don't drive 300 miles to Traverse City on coolant that can't do its job. For the full picture on summer overheating, read our [overheating action plan](https://primeotowing.com/blog/engine-overheating-detroit-summer).

Battery

Summer heat kills car batteries almost as effectively as winter cold. Heat accelerates the chemical degradation inside the battery — a battery that barely survived February may fail in August. Most auto parts stores will test your battery for free. If it's below 70% health, replace it before the trip.

Belts and hoses

Look at the serpentine belt: cracks, fraying, or a shiny glazed surface mean it's due for replacement. Squeeze the upper and lower radiator hoses — firm is good, spongy or rock-hard is bad. Check the connections for wetness or white/green deposits (signs of a slow coolant leak).

Wipers and washer fluid

Michigan summer means bugs, construction dust, and sudden thunderstorms. Worn wiper blades that streak are a visibility hazard in a downpour. Replace them ($20–$30) and fill the washer fluid reservoir.

Oil

If you're within 1,000 miles of your next oil change, do it before the trip. Driving 400 miles on oil that's already degraded puts extra wear on the engine, especially in heat.

Part 2: What to do when you break down on a Michigan highway

It happened. The car shuddered, the dashboard lit up, or the tire went flat. Here's the step-by-step.

Step 1: Get off the roadway

Signal, slow down, and pull as far to the right as you can — ideally onto a wide shoulder, a rest area, or an exit ramp. If you have a blowout, grip the wheel firmly, do not slam the brakes, and coast to a safe spot. On Michigan freeways, the right shoulder is almost always the safest option. Avoid stopping in a lane of traffic unless the vehicle is physically unable to move.

Step 2: Make yourself visible

Turn on your hazard flashers immediately. If you have reflective triangles or road flares, set them behind the vehicle — one at 50 feet, one at 100 feet, one at 200 feet. At night or in rain, this is critical. Staying visible is the single most important safety action you can take.

Step 3: Stay in or near the vehicle

On a busy freeway, standing outside the vehicle on the traffic side is more dangerous than the breakdown itself. If you must exit, exit from the passenger side (away from traffic) and stay behind the guardrail if there is one. If the car is in a dangerous position — stalled in a travel lane — and you can safely get out and away, move to the shoulder or tree line and call 911.

Step 4: Call for help

You have three options, and they're not equal:

**Michigan Freeway Courtesy Patrol (FCP).** MDOT's free roadside assistance patrols major Metro Detroit freeways — I-75, I-94, I-96, I-696, M-10, M-39, and US-24 — during peak commute hours (roughly 6–9 a.m. and 3–7 p.m., weekdays). They can jump-start your car, change a flat, deliver a gallon of gas, and help you merge back into traffic. If your breakdown happens during their hours on a covered freeway, they may find you before you even call. Outside their hours or on freeways they don't cover (I-275, US-23, I-69, US-131, US-31, any Up North highway), you need a tow company or [roadside assistance](https://primeotowing.com/services/roadside-assistance) service.

**Your roadside assistance plan.** AAA, manufacturer roadside (most new cars include 3–5 years), or your insurance company's roadside add-on. Response times vary — AAA's contract operators sometimes take 60–90 minutes on busy summer weekends, especially outside Metro Detroit. If you're in our coverage area, call us directly and skip the middleman.

**A tow company you already have saved.** This is the fastest option. Call [(313) 327-6334](tel:3133276334) and tell the dispatcher where you are, what happened, and where you want to go. We'll quote the full price before we roll and dispatch the right truck — [roadside for a quick fix](https://primeotowing.com/services/roadside-assistance), flatbed if the car needs a shop.

Step 5: Know when to tow vs. when to fix roadside

Quick roadside fixes that get you back on the road in 15–20 minutes:

• Dead battery → [jump start](https://primeotowing.com/services/jump-start)
• Flat tire with a good spare → [spare install](https://primeotowing.com/services/flat-tire-change)
• Out of gas → [fuel delivery](https://primeotowing.com/services/fuel-delivery) (2–3 gallons, enough to reach a station)
• Locked keys in car → [lockout service](https://primeotowing.com/services/lockout)

Tow-required situations:

• Engine won't start after a jump
• Overheating that won't stabilize (read the [overheating guide](https://primeotowing.com/blog/engine-overheating-detroit-summer))
• Transmission won't engage or the car won't shift
• Multiple flat tires or no spare available
• Visible fluid leak (coolant, oil, transmission fluid)
• Accident damage that makes the car undrivable
• Any situation where you don't feel safe driving

Part 3: After the breakdown — what to do next

Get the repair done before continuing

Don't "push through" to your destination on a car that just overheated, had a tire blow out, or threw a warning light. The car told you something is wrong. A $150 repair at a shop in Lansing is better than a $3,000 engine failure on the shoulder of US-131 outside Cadillac.

Save receipts for your insurance

If you have towing and labor coverage on your Michigan auto policy, your insurer will reimburse towing costs up to your coverage limit (typically $100–$200 per incident). Save the receipt from the tow and the receipt from the repair. Michigan's [optional towing coverage](https://primeotowing.com/blog/michigan-insurance-towing-coverage) is cheap to add and pays for itself on the first use.

Add a summer emergency kit

If this breakdown taught you that your trunk is empty, fix that before the next trip. A Michigan summer road trip kit should include:

• **Water** — at least a gallon, both for you and for the cooling system in an emergency
• **Phone charger** — a portable battery pack, not just a car charger (your car just died, remember)
• **Reflective triangles or road flares** — three minimum
• **Jumper cables or a portable jump pack** — a lithium jump pack is lighter than cables and works when there's no second vehicle around
• **Basic tools** — a lug wrench that fits your vehicle's lug nuts (aftermarket wheels sometimes need a different size), a flashlight, and work gloves
• **Tire pressure gauge** — digital is fine
• **First aid kit** — basics only
• **Rain poncho** — Michigan summer storms are sudden
• **Paper map or downloaded offline map** — cell signal is spotty in Northern Michigan and the UP
• **Sunscreen and bug spray** — if you're standing on a shoulder in July, you'll want both

Frequently Asked Questions

What is Michigan's Freeway Courtesy Patrol?

It's MDOT's free roadside assistance program that patrols select Metro Detroit freeways (I-75, I-94, I-96, I-696, M-10, M-39, US-24) during peak hours. The patrol trucks can help with jump starts, flat tires, small fuel deliveries, and minor mechanical issues. They won't tow your vehicle. The service is free — funded by Michigan taxpayers. Outside peak hours or on freeways they don't cover, you'll need to call a tow company or your own roadside assistance.

How far will a tow truck go for a summer road trip breakdown?

It depends on the company. Most local operators have a limited service area — 20 to 50 miles from their base. At Prime O Towing, our coverage runs across Metro Detroit, Washtenaw County, mid-Michigan, and into Northwest Ohio. For breakdowns beyond our area, we can do a [long-distance tow](https://primeotowing.com/services/long-distance-towing) back to Metro Detroit, or we can help you find a local operator where you are. Tell the dispatcher your location and destination — we'll tell you honestly whether we're the right call or whether someone closer can reach you faster.

Should I call 911 for a highway breakdown?

Call 911 if the situation is dangerous — stalled in a travel lane, an accident with injuries, a vehicle fire, or any scenario where other drivers are at risk. For a standard mechanical breakdown on the shoulder, 911 isn't the right call — they'll dispatch a state trooper who will then call a tow company anyway, adding time. Call a tow company directly, and dial 911 only if safety is at stake.

What if I break down in Northern Michigan or the UP where there's no cell signal?

This is real — large stretches of US-131 north of Cadillac, M-72, M-32, and most of the Upper Peninsula have spotty or no cell coverage. If you're planning a trip to Mackinac, Traverse City, Pictured Rocks, or anywhere north of Clare, download an offline map before you leave and consider a satellite emergency communicator. If you do break down without signal, your best bet is to stay with the vehicle with hazards on. Michigan State Police patrols most state highways, and other drivers often stop to help or report your location at the next town with signal.

Is a pre-trip inspection worth the money?

Most shops charge $50–$100 for a multi-point inspection that covers tires, brakes, fluids, belts, battery, and cooling. If they catch a failing water pump or a bald tire before your 400-mile trip, you've saved yourself a breakdown, a tow, a hotel night, and the stress of being stranded with your family on a highway shoulder. It's the cheapest insurance you can buy before a Michigan summer road trip.
