FAQ: Your Comprehensive Guide to Minibus Terminology for 2026
Entering the new year, EVM UK & Ireland wanted to provide a complete list of minibus terminology to help you, whether you are new to the world of minibuses or returning to expand your fleet.
Types of Minibus:
Minibus – A passenger vehicle, typically carrying up to 30 passengers, which is smaller than a bus but allows for transport of large groups.
Accessible Minibus – A minibus designed with community and ease of access in mind. EVMs Accessible minibuses aim to provide flexible, easy to use travel solutions for any level of mobility, often including lifts, ramps, durable materials and floor tracking systems.
Wheelchair Accessible Vehicle (WAV) – A vehicle specifically adapted to carry wheelchair passengers safely. All EVM Accessible Minibuses are WAV or WAV adaptable.

Midi Coach – A passenger vehicle that bridges the gap between a minibus and a coach, designed for more capacity than a typical minibus whilst remaining more manoeuvrable than a coach.
Minibus Conversion – The process of modifying a standard, reliable panel van into a passenger carrying vehicle. EVM stocks a variety of minibus conversions, most commonly Mercedes-Benz Sprinter and Iveco Daily conversions. By adding seats, improving interior comfort, and adding safety features, commercial vehicles become excellent quality minibuses.
Coach Built Minibus – The process of taking a chassis cab and mounting a purpose-built passenger vehicle body. This can provide a different aesthetic and more luggage room than a minibus conversion. EVMs Grand Tourer and Ferqui Range is an example of a coach built minibuses.
Ground Built Minibus – Rather than building from a commercial van, ground built refers to minibuses and coaches that are engineered specifically as a what their end product is.
Chassis/ Base Vehicle – The foundation of any vehicle, described as the base frame of a wheeled vehicle.
Tachograph – The Tachograph is a device that records information like driving time, speed and distance. This insures drivers and employers are following the rules about Drivers Hours. All EVM vehicles come pre-fitted with a Tachograph.
Guide Seat – An additional passenger seat, typically foldable and unobstructive, which allows for crew/ a guide to be seated near the driver, without taking a seat from passengers.
Regulations:
GSR2(General Safety Regulation 2) – An EU law which mandates advanced driver assistance systems in new vehicles to improve road safety.
PSVAR(Public Service Vehicles Accessibility Regulations) – UK laws that require buses and coaches to be accessible for disabled passengers, aiming to provide equal access with features like wheelchair accessibility and clear audio/visual information. On vehicles with over 22 seats used for local or scheduled services, PSVAR mandates features like lifts, ramps, and priority seating.
PSVAIR (Public Service Vehicle Accessibility Information Regulations) – Building on PSVAR, PSVAIR focuses on ensuring every passenger using local transport services has access to high-quality on-board information at all times. PSVAIR refers to technology like audible systems, visual displays and hearing loops. To learn more about the differences between PSVAIR and PSVAR, click here to read our article here >>>
PSV – A minibus or coach used to carry fare-paying or contracted passengers.
PSVAIR Prep – An industry term, meaning a minibus or midi coach is wired and set up so SVAIR equipment can easily be installed.
GB type-approval category – Vehicles are classified based on their passenger capacity and weight which is used for safety regulations like GSR2 or licensing:
M1 – up to 8 passenger seats
M2 – more than 8 passenger seats, up to 5 tonnes
M3 – more than 8 passenger seats, over 5 tonnes
Grandfather rights – Drivers who passed their car test before 1 January 1997 may have “grandfather rights” giving them D1 entitlement automatically. This can be checked on the back of a license.
Licenses – Depending on the amount of passengers and weight of vehicle you are looking at, depends on which license you may require. Click here to read our full article >>>
