Glossary of car and van rental terms

Last Updated: 18 September 2026

If you're planning to rent a car or van, you might encounter some unfamiliar terms and phrases used by rental companies. These terms can often be confusing and sometimes misleading, making the process somewhat intimidating.

To help you understand what these buzzwords mean and avoid unwanted surprises when you pick up and return your vehicle, we created a complete glossary of rental terms to prepare you for your next excursion.

A complete glossary of vehicle rental terms

Here are some of the key terms that you should know before renting a car or van in alphabetical order:

Car-Derived Van

A car-derived van — the smallest size of van available — as the name suggests, is based on a regular passenger car. They are often more fuel-efficient than other types of vans, but they also have much less cargo space.

CDW (Collision Damage Waiver) 

A CDW, also known as LDW (Loss Damage Waiver), is an optional insurance that reduces your liability for damage to your rental vehicle. It typically covers the cost of repairs in an accident, regardless of fault, and requires you to agree to an excess fee.

Child Seats

Child seats are safety restraints designed to protect young children in the event of an accident. They are divided into three categories: rear-facing, forward-facing, and booster seats. 

Deposit 

A deposit is the sum of money that you'll likely have to pay upfront when you rent a vehicle. The rental company holds it as security against damage to the vehicle, and refunds it when you return the vehicle in good condition. 

Excess 

Excess is the amount you may have to pay out of pocket if your vehicle is damaged or stolen during your rental period. It is usually deducted from your deposit or charged to your card. 

Flexible Hire 

Flexible hire lets you rent a vehicle for as little as one week and return it whenever you need to—no long-term contracts or commitments —so you can cancel at any time. 

Long-Term Hire

Long-term hire refers to a rental period that is typically longer than one month. Businesses that need a fleet of vehicles, or students who need a car for the school year, often use this type of rental. 

Luton Box Van 

A Luton box van is designed to maximise storage space. They quite literally look like a box on wheels and are typically used for moving houses and transporting bulky items such as furniture or appliances. 

LWB (Long Wheelbase)

LWB stands for Long Wheelbase and refers to vans that have a greater length between the front and rear wheels than SWB vans. LWB vans are usually larger and more spacious so that they can accommodate more passengers or cargo. Be aware, they are often more difficult to park and manoeuvre.

MPV (Multi-Purpose Vehicle)

MPV stands for Multi-Purpose Vehicle. This type of vehicle is designed to be versatile and practical thanks to its larger interior space, which allows it to seat between seven and nine people or carry extra luggage. At Rent Direct, we have a variety of MPVs available for hire. 

Payload

Payload refers to the maximum amount of weight a vehicle can carry, including passengers, cargo, and fuel. Knowing your van's payload is important, as overloading it can damage the vehicle and result in legal penalties.  

Rental Agreement

The rental agreement is a legally binding contract between you and the rental company that specifies the terms and conditions of the rental. The rental agreement is an important document and should be read carefully before you sign it. 

Roadside Assistance

Roadside assistance is a service that helps motorists who experience mechanical breakdowns or other roadside emergencies. This can include flat tyres, towing, and jump starts. Rental companies may offer roadside assistance to give you peace of mind while on the road.

Satellite Navigation (GPS) 

GPS is a navigation system that uses satellite signals to determine your location. It is usually built into cars and vans to help drivers find their destination and avoid traffic congestion. 

Short-Term Hire

Short-term hire refers to a rental period that is typically less than one month. This type of rental is often used for holidays, business trips, or other short-term needs.

Surcharge 

A surcharge is an additional fee charged for various reasons and depends on the vehicle type, rental company, and location. Some common surcharges you may incur include:

• Young driver surcharge for drivers under a certain age
• Senior driver surcharge for drivers over a certain age
• Additional driver surcharge for adding more than one driver to the rental agreement
• One-way surcharge for returning your vehicle to a different location than where you picked it up
• Out-of-hours surcharge for picking up or dropping off the vehicle outside the normal opening hours of the rental location
• Fuel surcharge for returning the vehicle with less fuel than when you picked it up
• Mileage surcharge for exceeding the allowed mileage limit
• Airport surcharge for renting a vehicle from an airport location
• Environmental surcharge for renting a vehicle that emits more CO2 than average 

SWB (Short Wheelbase)

SWB stands for Short Wheelbase and refers to vans that have a shorter length between the front and rear wheels than LWB vans. SWB vehicles are usually medium-sized and more compact, ideal for city driving, short trips, or parking in smaller spaces.

Tail Lift 

A tail lift is a hydraulic platform at the rear of a vehicle that can be raised or lowered to make it easier to load and unload heavy items. You can often find them on the rear of Luton box vans.

Theft Protection 

Theft protection is a type of insurance that covers the cost of replacing a rental car if it is stolen. It is typically offered as an optional add-on to the rental price.

Transmission

Simply put, transmission refers to whether the vehicle shifts gears manually or automatically. Knowing whether a rental vehicle has a manual or automatic transmission matters for drivers who have only experience with one type.
