Truck breakdowns in NC: triangles, IMAP, towing and night repairs

The short version

Turn on your flashers the moment you stop, and get three warning triangles out within 10 minutes. North Carolina law points straight at the federal rule for this. [10][1]

NC's move-over law protects tow trucks, patrol trucks and road crews. It does not cover a plain broken-down truck with its hazards on. Your triangles are your protection. [2][9]

From a cell phone, *HP (*47) reaches the Highway Patrol. NCDOT's free safety patrol, IMAP, can bring a little fuel, jump a battery or change a tire, but it is mostly a daytime service. [19][26]

If the Highway Patrol calls a rotation wrecker, its fees are capped at that company's normal rates. After-hours towing can cost at most 10% more, and storage starts the next day. [3][16]

Flashers now, triangles within 10 minutes

Under 49 CFR 392.22, when a truck is stopped in a travel lane or on the shoulder for anything but a traffic stop, the hazard flashers go on right away. They stay on until the warning devices are out. [10]

The warning devices must be placed as soon as possible, and within 10 minutes at most. Flashers can stay on too, but they don't replace the devices. [10]

On a two-way road, put one device about 10 feet behind the truck on the traffic side, one about 100 feet behind, and one about 100 feet ahead. [10]

On a divided or one-way highway, put them about 10, 100 and 200 feet behind the truck, toward the traffic coming at you. [10]

Near a curve, hill crest or anything else that blocks the view within 500 feet, the rule says to set one device 100 to 500 feet back so drivers see it in time. [10]

Every power unit must carry three reflective triangles, or at least six fusees. Trucks hauling certain explosives, flammable liquid or flammable gas tanks, empty or loaded, can't use fusees or flames. [11]

As of a February 2026 change, the federal rule names fusees but no longer lists liquid-burning flares. And G.S. 20-161(c) requires the driver of a disabled truck or trailer to show these devices for as long as it is disabled. [10][1]

NC law also says not to leave a vehicle in a travel lane unless it is too disabled to avoid it. On the shoulder, it must be visible from 200 feet both ways. [1]

The move-over law won't cover your truck

G.S. 20-157(f) makes drivers move over or slow down for emergency vehicles and "public service vehicles" stopped within 12 feet of the road with warning lights on. Our NC traffic laws guide explains the full rule. [2]

Public service vehicles include tow trucks, IMAP trucks, utility crews, garbage trucks and highway maintenance trucks. A private truck that has simply broken down is not on the list. [2][23]

A 2023 bill, Senate Bill 638, would have added disabled vehicles showing hazard lights or flares. It passed the Senate 49-0 but was sent to the House Rules committee in May 2023 and did not become law. [9]

That changes once help arrives. When a wrecker or IMAP truck parks behind you with its lights on, passing traffic must move over for that vehicle. [2][19]

NCDOT said in November 2025 that almost two dozen incidents that year involved passing drivers hitting IMAP trucks or responders. Good triangle spacing buys everyone room. [25]

Who to call, day or night

NCDOT tells drivers who break down on the interstate to dial *HP from a cell phone. In areas the safety patrol covers, *HP is also how you ask for IMAP. [20][19]

Call 911 if anyone is hurt, there is a fire or leak, or the truck is stuck in a live lane. That's our advice for emergencies, not a special NC rule. [1][4]

511 is for road conditions and closures, not rescue. As of August 2026, live operators answer weekdays from 8:15 a.m. to 7:45 p.m. and weekends from 8:15 a.m. to 4:45 p.m. [21]

Overnight there is no live 511 operator. NCDOT points drivers to DriveNC.gov, which shows crashes, closures and rest areas. [21]

If you had a minor crash and both vehicles still drive safely, the "fender bender" rule in G.S. 20-166(c2) says to move them out of the travel lanes to the shoulder or another safe spot. [4][26]

What NCDOT's IMAP patrol can do for a truck

NCDOT's Safety Service Patrol, called IMAP, is free. Its responders change flat tires, hand out small amounts of gasoline or diesel, and jump-start batteries. [19]

The trucks carry arrow boards, cones, fuel, water, air, jumper cables, jacks, push bumpers and winches. Their job is to clear the lanes and protect the scene. [19]

NCDOT's training guide says an IMAP truck can push a loaded tractor-trailer in good conditions. That is to clear a lane, not a tow to a shop. IMAP is not a wrecker or a mechanic. [27]

As of August 2026, NCDOT lists more than 100 responders statewide, in blue-and-white trucks sponsored by GEICO. Responders can't contact the sponsor or help with insurance claims. [19]

Coverage is mostly on busy routes. Urban patrols usually run two weekday shifts around rush hours. In 2025, the Charlotte, Triad and Triangle areas added weekend shifts on their busiest routes. [26]

Rural routes usually get one shift. In August 2025, NCDOT extended IMAP on I-26 down to the South Carolina line, including the Saluda Grade. [26][24]

So don't count on IMAP at 2 a.m. If your truck carries hazardous materials, NCDOT's manual says neither NCDOT nor the Highway Patrol should move it. Hazmat teams handle it. [26]

If you can't move it, someone else will

G.S. 20-161(f) is NC's quick clearance law. An officer, with NCDOT's OK, or NCDOT, with an officer's OK, can immediately remove a disabled vehicle or its cargo if it blocks traffic or is a hazard. [1][26]

The officers, NCDOT and its contractors are not liable for damage done in the removal. Under G.S. 20-161(g), the owner pays for removal, storage and disposal of the vehicle and cargo. [1]

A vehicle left on the highway right-of-way, rest areas included, for 24 hours or more can be towed and stored by an officer under G.S. 20-161(e). [1]

In some interstate work zones, NCDOT stages contract tow trucks. As of NCDOT's June 2026 page, they cover parts of I-40 in Orange and Haywood counties and I-95 south of Fayetteville. [20]

A move to a nearby safe spot costs you nothing. A tow to a shop, storage, cleanup or on-site repair is billed to the owner. You don't have to use the contract tower beyond that first move. [20]

Highway Patrol rotation tows and what they can charge

When the Highway Patrol calls a wrecker, it uses a rotation list. G.S. 143B-1716, formerly G.S. 20-188, says rotation fees can't exceed what the same company charges non-rotation customers. [3]

Each zone keeps separate large and small wrecker lists. A large wrecker has a chassis rated at least 26,001 pounds and a boom rated at least 40,000 pounds. [17]

The rotation rules in 14B NCAC 07A .0116 say towing fees after 5 p.m. and on weekends can be no more than 10% above business-hours fees. [16]

Storage fees don't start until the next calendar day. You aren't charged storage for days you couldn't get the truck back because the company was closed or couldn't be reached. [16]

The wrecker driver must carry the approved price list and give it to you if you're at the scene. Listed prices are maximums, and non-hazardous debris cleanup is not billed extra. [16]

Personal property, which the rule defines to include freight, must be returned on request whether or not the tow bill is paid. A mileage fee applies only if you ask for a tow out of the zone. [16]

For fee disputes, an NCSHP spokesman told WLOS in 2018 to go to the district's First Sergeant, who oversees rotation wreckers. Confirm the current contact with your local Patrol troop. [28][16]

If an officer had your truck towed, G.S. 20-219.11 lets you ask a magistrate for a hearing on the tow. Under G.S. 20-219.12, you can get the truck back by paying or posting a bond. [7][8]

Limping to a shop, and out-of-service orders

Under 49 CFR 396.7, a truck found unsafe on the road may only go on to the nearest place it can be safely repaired, and only if that is less risky than leaving it on the highway. [13]

At night, lights matter. 49 CFR 393.9 says every required lamp must work at all times, so a dead tail or clearance light is a real problem, not a small one. [15]

NC's 59 rest areas are open 24 hours, per NCDOT's rest area page. They have restrooms and water, but no truck repair. [22]

If an inspector puts the truck out of service, nobody may drive it until repairs are done. Only a wrecker's crane or hoist can move it, and the sticker stays on until then. [14]

The carrier must certify the repairs and, if the state asks, return the form within 15 days of the inspection, then keep a copy for 12 months. Keep the repair receipts with it. [14]

Our advice, not a rule: before you roll, save your carrier's breakdown number and your roadside or tow coverage. When you call, give the mile marker and direction, and ask for price and arrival time first. [21][16]
