Yes, you can usually drive a car with a broken trunk, but it is often illegal and always unsafe. The primary risk is that the trunk lid could fly open while driving, obstructing your rear view and creating a hazard for other motorists. Contents inside could also fall out onto the road. Most states have vehicle safety laws that require all doors, including the trunk, to be securely closed or latched. Driving with an unsecured trunk can result in a traffic citation for an unsecured load or an obstructed license plate.
The immediate steps you take depend on how the trunk is broken. If the latch is malfunctioning but the trunk can be closed, you may be able to secure it temporarily with strong rope or bungee cords looped through the trunk latch and connected to the rear tow hooks. However, this is a short-term fix. If the trunk cannot be closed at all, you should remove any valuable or loose items and drive directly to a repair shop, using side and rearview mirrors with extra caution.
The long-term solution involves diagnosing the problem. Common causes for a trunk not staying shut include a broken latch mechanism, a faulty trunk release cable, or damaged hinges. The repair cost can vary significantly based on the issue and your car's make and model.
| Common Trunk Issue | Typical Repair Cost Range | Complexity | Common Fix |
|---|---|---|---|
| Broken Latch Mechanism | $150 - $400 | Moderate | Replacement of the latch assembly |
| Faulty Actuator/Solenoid | $200 - $500 | Moderate | Replacement of the electronic actuator |
| Misaligned Striker | $75 - $150 | Low | Adjusting the position of the metal striker plate |
| Broken Release Cable | $100 - $250 | Moderate | Replacement of the manual release cable |
| Damaged Hinges | $250 - $600+ | High | Welding or replacement of damaged hinges |
Ignoring a broken trunk can lead to secondary issues like water damage to the interior during rain or a drained car if the trunk light remains on. For safety and legal reasons, getting it repaired promptly is the responsible course of action.

Been there. I drove for a week with a bungee cord holding my trunk down after the latch snapped. It’s doable, but you have to be . First, clear out anything that could fly out. Second, tie it down tight—use the tow hooks under the bumper, not just the latch. Check your rearview mirror constantly because your visibility will be compromised. It’s a hassle, and you’ll get some looks, but it can get you to the mechanic. Just don’t put it off; it’s not worth the risk.

Legally, it's a gray area that depends on local enforcement. The main concerns for police would be an unsecured load and an obstructed license plate. If your trunk is tied down securely and your plate is visible, you might be okay for a short, slow drive to a repair shop. However, if the trunk is flapping open, you are almost guaranteed to be pulled over. The safest bet is to treat it as an unsafe vehicle and minimize driving until it's fixed.

My main worry would be and the elements. If the trunk won't lock, you can't leave anything of value in the car. Even a grocery run becomes a problem. Plus, if it rains, water will get into the trunk and then likely into the cabin, leading to mold and mildew. I’d focus on getting it to a body shop immediately. Ask them if they can prioritize just securing the latch so you can drive safely, then schedule a full repair later when it's convenient.

From a pure safety standpoint, a compromised trunk is a significant risk. The aerodynamic forces at highway speeds can easily rip a poorly secured trunk lid open, causing a sudden loss of rear visibility and potentially striking another vehicle. It also compromises the structural integrity of the vehicle in a rear-end collision. Your priority should be to have the vehicle towed to a repair facility. If you must drive, do so at low speeds on local roads for the shortest distance possible. The risk far outweighs the convenience.
