What must be verified if you pick up a customer aged 18?

When considering the scenario of picking up a customer who is 18 years old, verifying full coverage insurance is crucial. This is primarily due to the fact that young drivers, particularly those who are still classified as new drivers, statistically engage in riskier driving behaviors. Insurance companies often have policies in place that require full coverage for young adults to mitigate potential financial loss resulting from accidents. Additionally, many leasing or rental companies mandate that young renters over a certain age have full coverage insurance to protect both the company and other drivers on the road.

In this context, having full coverage provides a layer of financial security that helps ensure that if any damage occurs, it's covered by the insurance. This requirement is particularly important for drivers in the 18-24 age range, who are frequently considered higher risk.

The other options presented do not align with mandatory industry standards or common practices in rental and leasing scenarios. While having a co-signer, charging a higher security deposit, or requiring previous customer status may be policies some organizations choose to implement, they are not universally necessary for all transactions involving an 18-year-old customer. Verifying full coverage insurance is a more consistent and standardized requirement that directly relates to risk management in vehicle rentals or leases.
