Breaking down on a Utah highway is more than just inconvenient — on mountain passes, in canyon country, or during a winter storm, it can be genuinely dangerous. The difference between a minor hassle and a serious situation often comes down to what's in your car. This checklist covers the essentials for Utah drivers, from basic urban breakdowns to remote canyon emergencies.
Tier 1: The Absolute Essentials (Keep These No Matter What)
These items should be in every car, every time. No exceptions.
✅ Jumper Cables or Jump Starter Pack
A dead battery is the most common roadside emergency. Traditional jumper cables require another vehicle; a portable jump starter (also called a jump pack or battery booster) lets you start your car independently. Modern lithium-ion jump packs are compact (fits in a glovebox), powerful enough for most vehicles, and can also charge your phone. Budget $40–$100 for a quality unit.
Note for EV/hybrid owners: Standard jumper cables cannot jump-start high-voltage EV batteries. They can jump-start the 12V auxiliary battery that some systems need, but if you have an EV and lose your main charge, you need a tow — not a jump. See our EV towing guide for more.
✅ Spare Tire, Jack, and Lug Wrench
Check that your spare tire is actually inflated and that you know where your jack and lug wrench are stored. Many drivers have never looked. Check them now, before you need them. If your vehicle came with a space-saver "donut" spare: maximum speed 50 mph, maximum distance 50 miles — donut spares are for getting to a tire shop, not for highway driving.
✅ Reflective Warning Triangles or Flares
If you break down on a highway, you need to alert approaching drivers. Three reflective triangles should be placed at 100, 200, and 300 feet behind your vehicle. LED flares (battery-powered) are safer than traditional flares and reusable. On Utah's I-15 and I-80 where traffic moves at 80 mph, visibility is life-critical.
✅ Flashlight and Extra Batteries (or Rechargeable)
Never rely solely on your phone flashlight. A dedicated LED flashlight with fresh batteries costs $10–$25 and provides far more reliable illumination for engine inspection or changing a tire at night.
✅ Phone Charger Cable + Car Adapter or Power Bank
Your smartphone is your emergency lifeline. A dead phone when you're broken down on Highway 6 at night is a serious problem. Keep a charged power bank in your kit (recharge it periodically — power banks self-discharge over months).
✅ Basic First Aid Kit
Bandages, antiseptic wipes, gauze, medical tape, pain relievers, and nitrile gloves. A basic kit is adequate; a more complete one with a tourniquet and QuikClot gauze is worth carrying if you travel remote Utah roads regularly.
Tier 2: Highly Recommended for All Utah Drivers
✅ Tire Inflator / Portable Air Compressor
A slow leak or underinflated tire doesn't always require a tow — often you can inflate it enough to reach a tire shop. A 12V portable air compressor plugs into your car's power outlet and costs $25–$60. Also useful for filling your spare before you need it.
✅ Tire Plug/Patch Kit
Many flat tires are caused by nails or screws that can be plugged in 10 minutes with a basic kit ($10–$20). This is a viable roadside repair for punctures in the tread (not sidewall). Plug it, inflate it, drive to a tire shop for a proper repair.
✅ Tow Strap
If you go off the road into soft dirt, sand, or snow (common in Utah), a tow strap lets a passing motorist help pull you out. Get a nylon recovery strap rated for at least 20,000 lbs. These are not tow ropes — recovery straps have elasticity that helps extract stuck vehicles. A good strap runs $20–$40.
✅ Multi-Tool or Basic Tool Kit
A quality multi-tool (Leatherman, Gerber) handles countless small roadside needs. Supplementing with a small kit (screwdrivers, pliers, zip ties, duct tape, electrical tape) covers most minor mechanical issues. Zip ties and duct tape have saved countless roadside situations.
✅ Water — At Least 1 Gallon Per Person
This is non-negotiable in Utah. Southern Utah reaches 115°F in summer. The desert stretches between St. George, Moab, and Green River are remote. Even around Salt Lake City, summer heat can make a roadside wait genuinely dangerous without water. Keep water in your car and rotate it seasonally.
✅ Snacks / Energy Bars
A few protein bars or trail mix bags add minimal weight but keep energy up during long waits. Useful for kids in the car too.
✅ Blanket
Both a thermal space blanket (compact, $3–$5) and a heavier wool or fleece blanket are useful. The thermal blanket fits in your glovebox; the heavier blanket keeps you warm if you have to wait hours in winter cold.
Tier 3: Utah Winter/Mountain Essentials (October–April)
If you drive Utah canyons or mountain passes in winter, this tier is as essential as Tier 1.
✅ Ice Scraper and Snow Brush
Utah's valley temperature inversions can produce ice on your car even when roads are clear. A quality ice scraper with a long handle for the roof is essential.
✅ Snow Shovel (Compact)
A compact, foldable avalanche shovel is worth having if you drive Parley's Canyon, Big Cottonwood Canyon, or Highway 189. Getting high-centered or buried in snow drifts is more common than most drivers think.
✅ Tire Chains or Traction Devices
Utah requires chains or snow tires with traction devices on certain mountain roads when conditions require it. True tire chains provide the most traction; AutoSock or ISSE traction sleeves are easier to install and work well in moderate snow. Check your tire clearance — many modern vehicles have insufficient wheel well clearance for standard chains.
✅ Sand or Cat Litter (Traction Aid)
A small bag of sand or cat litter spread under spinning tires provides enough traction to get unstuck from ice or compacted snow. Inexpensive and often the simplest way to get moving again.
✅ Extra Warm Clothing
Gloves, a hat, and an extra jacket stored in a bag in the trunk. If you break down on I-80 near Park City in January, waiting for a tow truck in dress clothes is genuinely dangerous. Utah mountain temperatures drop below 0°F regularly.
✅ Hand Warmers
Chemical hand warmers are cheap, pack flat, and can prevent frostbite while you wait for help. Keep 4–6 pairs in your kit through winter.
Your Emergency Contact List
Your kit is only as good as your ability to call for help. Save these numbers in your phone before you need them:
- Utah Highway Patrol: 801-965-4461 or *11 from your cell phone
- UDOT Traffic Operations: 511
- Your roadside assistance plan (AAA, manufacturer roadside, insurance)
- A trusted local tow company (find one before you need it at National Tow Connect directory)
