Which of these is NOT a common example of a contract violation with rental vehicles?

Returning the vehicle too early is typically not considered a common violation of the rental contract. Most rental agreements focus on the duration for which the vehicle is rented, and while returning it late may incur extra charges, returning it earlier than agreed is usually allowed, sometimes resulting in a refund for unused days depending on the rental company’s policies.

In contrast, leaving the keys in the car can be viewed as a security issue and a violation of responsibility for the rental, towing a rental vehicle without authorization is generally prohibited as it can disrupt rental agreements, and driving the vehicle out of state without prior permission often breaches the terms of the contract regarding vehicle use. Therefore, option B stands out as not aligning with the primary concerns surrounding typical contract violations in rental agreements.
