If you own a quad bike or are thinking of buying or renting one, it is essential to know whether it is approved for two people. Not only for convenience, but also because riding with a passenger on a vehicle that is not approved for this purpose can lead to serious penalties and, above all, put you and your passenger’s safety at risk.
In this article, I will explain how to check the homologation of your quad, the differences between a single-seater and a two-seater, and what to do if you need to homologate it to carry a passenger.
What does it mean for a quad to be homologated for two people?
When we talk about the homologation of a two-person quad, we mean that the vehicle has been designed, tested and certified by the competent authorities to carry a passenger in addition to the driver.
This process is not only an administrative matter, but also implies that the quad has the necessary structural and safety conditions to carry two people safely.
Some key features of two-seater quads are:
- Longer seat or seat with backrest, so that the passenger rides comfortably.
- Additional footrests, ensuring a stable foothold.
- Reinforced chassis, to support the extra weight without compromising stability.
- Adapted suspension and brakes, allowing better control with two occupants.
If a quad does not have these elements and is not homologated in the technical data sheet for two seats, it is NOT allowed to carry passengers.
How to identify if your quad is homologated for two seats?
To find out if your quad is a two-seater, there are three basic methods you can check:
Consult the vehicle’s technical data sheet
The technical data sheet is the official document that details the characteristics of the quad. In the ‘number of seats’ section, it should say ‘2’ if it is approved to carry a passenger.
If ‘1’ appears on the technical data sheet, it means that the quad is a single-seater and you cannot legally carry another person.
Check the registration certificate
Another document where you can check the homologation is the registration certificate. This document also indicates whether the vehicle is authorised for one or two seats.
Visual inspection of the quad bike
If you do not have access to the documents, you can make a visual inspection. Some clear signs that a quad is a two-seater are:
- A long seat with enough room for a passenger.
- Rear footrests for the passenger.
- Handlebars or rear backrest for the passenger to hold on to.
If your quad does not have these items, it is likely to be a single-seater, although it is always best to check with the official documents.
Differences between single and two-seater quads
While quads may look similar at first glance, there are notable differences between single and two-seater models.
Single-seater quad:
- Designed exclusively for one person.
- Lighter and more compact structure.
- Greater manoeuvrability, ideal for uneven or sporty terrain.
- It does not have a rear seat or support for a passenger.
Two-seater quad:
- Homologated for two people.
- Larger and more comfortable seat.
- Reinforced chassis to support the extra weight.
- Suspension and brakes adjusted for stability with two occupants.
If you are planning to do a quad tour of 1 hour or more with a companion, it is essential that you choose a two-seater model. Not only for safety reasons, but also because you could get a fine if you are stopped at a checkpoint.
Can a two-person quad bike be homologated?
If you already have a single-seater quad and would like to be able to take a passenger, it is possible to homologate it as a two-seater, although it is not a simple or inexpensive process.
Technical requirements for homologation
To convert a single-seater quad into a two-seater, the vehicle must meet certain requirements:
- Reinforced chassis and structure: Some models do not allow homologation because their structure does not support the additional weight.
- Adequate rear seat: It must comply with the dimensions and ergonomics established by the regulations.
- Rear footrests and handgrips: Mandatory to ensure passenger safety.
- Adapted suspension and brakes: You may need mechanical modifications to ensure control of the quad with two people.
Approval process
- Consult an engineer specialised in vehicle homologations.
- Installation of the necessary elements in a certified workshop.
- Technical inspection at the MOT to verify that the quad complies with the regulations.
- Modification of the technical data sheet and updating of the registration certificate
Associated costs
The cost of homologating a two-person quad bike can range from 600 to 2,000 euros, depending on the model and the modifications required. In some cases, it may be more cost-effective to sell your single-seater quad and buy a two-seater directly.
Consequences of carrying a passenger on a non-approved quad bike
If you decide to take a passenger on a quad that is not approved for two people, you should be aware that you risk various penalties and legal problems:
- Financial penalties: Penalties can exceed 200€ in Spain.
- Loss of licence points: Depending on the offence, you could lose up to 4 points on your driving licence.
- Risks in the event of an accident: In the event of an accident, the insurance may not cover the damage if the quad is not approved for two people.
- Problems with the ITV: If you modify a quad without official approval, you may not pass the Technical Vehicle Inspection (ITV).
Therefore, if you are planning to buy or rent a quad bike, make sure that the vehicle is a two-seater if you are going to take a passenger.
Safety and legality when driving a quad bike
Knowing whether a quad is approved for two people is key to ensuring your safety and avoiding penalties.
- Always check the technical data sheet and the registration certificate.
- If the quad is a single-seater, you CANNOT take a passenger.
- It is possible to homologate a two-person quad, but it is expensive and requires technical modifications.
- If you are going to rent a quad, check that it is a two-seater if you are going with a passenger.
By following these recommendations, you will be able to enjoy a safe and worry-free experience.
