Driving Other People’s Cars – Am I Allowed & What Are The Rules?

Borrowing a car can be straightforward or complex, depending on the situation. Whether it’s for a quick errand, visiting friends, using a business vehicle, or driving with a learner’s permit, understanding the nuances of each scenario ensures you remain on the right side of the law. Some questions might get into your mind like What are the restrictions? Is it legal to drive someone else’s car? How about the Insurance? Below, we break down what you need to know into rules and regulations, documentation needed, and other necessary information for each circumstance.

Different Scenarios

Quick Errand

Rules and Regulations: The fundamental rule here is obtaining the car owner’s permission. Legally, you’re required to have at least the minimum insurance coverage mandated by your jurisdiction. Since insurance usually follows the car, you’re likely covered under the owner’s policy.

Documentation Needed: Ensure you have a valid driver’s license on you. No additional documentation should be needed, though having proof of the owner’s insurance in the vehicle is wise.

Other Necessary Information: Double-check the insurance policy for any restrictions on additional drivers. Some policies might exclude certain age groups or require that additional drivers be named on the policy.

Visiting Relatives or Friends

Rules and Regulations: Similar to borrowing for a quick errand, the key is permission and insurance. For extended stays, the vehicle’s owner may need to notify their insurance provider to ensure continuous coverage.

Documentation Needed: A valid driver’s license and access to the car’s insurance information are necessary. If you’re staying for a while, consider carrying a note from the owner that states you have permission to use the car.

Other Necessary Information: Familiarize yourself with local traffic laws, especially if you’re visiting from out of state or a different country. Differences in speed limits, traffic signals, and road etiquette can lead to unintended violations.

Borrowing a Business Vehicle

Rules and Regulations: Ensure the vehicle is insured for business use, and check if you need to be officially listed as an authorized driver, especially for regular use.

Documentation Needed: A valid driver’s license and proof of the vehicle’s commercial insurance coverage. Sometimes, a letter or ID badge proving your affiliation with the business is necessary.

Other Necessary Information: Be clear on what the vehicle can and cannot be used for according to company policy. Personal use might be restricted or entirely prohibited.

Having a Learner’s Permit

Rules and Regulations: The supervising driver must meet the criteria set by your region—usually involving age and years of driving experience. The learner must be added to the car owner’s insurance policy to ensure coverage.

Documentation Needed: The learner’s permit itself, and potentially documentation proving the supervising driver’s eligibility. Also, proof of insurance coverage that includes the learner driver.

Other Necessary Information: It’s crucial for learners to be aware of any restrictions tied to their permit, such as driving hours or the number of passengers allowed.

Car Rentals: Stateside and International

Rules and Regulations: Insurance is a critical component of renting a car. For example, let’s say you’re visiting Ireland and you’re wondering if you can put your child with a learner’s permit down as a driver. After, you learn that the insurance through most rental car companies won’t cover someone who doesn’t have a full license yet.

In most countries, car rental companies require the driver to be a certain age, typically 21 or older, although this can vary. There’s often an additional fee for drivers under a certain age threshold, usually 25.

Documentation Needed: A valid driver’s license from your home country is required, and if you’re renting a car abroad, you may also need an International Driving Permit (IDP). The IDP translates your license into several languages and is recognized in over 150 countries. Additionally, you’ll need a credit card in your name to hold the reservation and cover any deposits.

Handling Emergencies and Unexpected Situations

When you’re driving a car that isn’t yours, it’s crucial to know how to manage emergencies like breakdowns or accidents and understand the potential traffic violations and penalties.

Breakdowns and Accidents

If the vehicle you’re driving breaks down, your first step is to ensure your safety and that of other road users. Pull over to a safe location, turn on hazard lights, and set up emergency triangles if available. Immediately contact the owner of the vehicle and their insurance company for guidance on roadside assistance and next steps. 

In case of an accident, prioritize safety and exchange information with the other party involved. After ensuring everyone’s well-being, it’s important to document the scene with photos and contact the authorities if necessary. Always report the incident to the car owner and their insurance provider as they will instruct you on how to proceed with the claims process.

Traffic Violations and Penalties

When you’re behind the wheel of someone else’s car, you’re still responsible for adhering to traffic laws. Any tickets or fines incurred are your responsibility, not the car owner’s. Be aware that different locations may have varying rules and penalties. 

In case you receive a traffic violation, it’s essential to inform the car owner, as the ticket may be sent to their address. Ensure timely payment or contest the ticket if you believe it was a mistake. Neglecting traffic violations can lead to escalated penalties and legal issues, which can complicate your situation and create trouble for the car owner.

  • Traffic Law Compliance:
    • Understand you’re responsible for violations
    • Inform car owner of any tickets
    • Pay fines promptly or contest errors
    • Avoid neglecting tickets to prevent additional penalties


Driving someone else’s car requires a blend of legal understanding, proper documentation, and a clear communication channel with the car owner. By paying close attention to the rules and regulations, ensuring all necessary documentation is in order, and considering other essential information, you can navigate borrowing a car with confidence and responsibility.
