Modern UK buses must meet strict accessibility standards. Here's what terms like "low-floor", "kneeling", and "PSVAR" actually mean.
What is PSVAR?
PSVAR stands for Public Service Vehicles Accessibility Regulations. These UK regulations (introduced 2000) set minimum accessibility standards for buses and coaches.
Since 1st January 2017, all single deck buses on local services must be PSVAR compliant. Since 1st January 2020, all double deck buses must comply too.
Key PSVAR requirements
Wheelchair space: At least one designated wheelchair area with proper restraints
Low floor: Step-free access from the kerb to the wheelchair space
Ramp or lift: A way to bridge the gap between bus and pavement
Colour contrast: Handrails, poles and step edges must contrast visually
Priority seating: Clearly marked seats near the front for those who need them
Audible announcements: Next stop information (required on some services)
What "low-floor" means
A low-floor bus has no internal steps between the entrance and the main passenger saloon (at least for part of the bus). This allows:
Wheelchair users to board without a lift
Pushchairs and shopping trolleys to roll straight on
Faster boarding for everyone
Easier access for passengers with mobility difficulties
What "kneeling" means
Many modern buses can "kneel" - the suspension lowers the entrance side of the bus closer to the kerb. This reduces the step height even further, making boarding easier for everyone.
Drivers typically activate kneeling at stops, and the bus rises back to normal height before moving off.
Ramps vs lifts
Ramps: Most common on UK buses. A manual or powered ramp folds out from the doorway to bridge the gap to the pavement.
Lifts: Less common in the UK. A platform that raises/lowers passengers. More often seen on coaches.
The wheelchair space
PSVAR requires a designated wheelchair space with:
Minimum dimensions (750mm × 1300mm for most buses)
A backrest or padded surface
A way to communicate with the driver
Clear signage
Note: This space is often shared with pushchair/buggy users. Wheelchair users have priority - this was confirmed in the 2017 Supreme Court case FirstGroup v Paulley.
Next stop displays: Visual screens showing upcoming stops
Audio announcements: Automated or driver announcements (increasingly common)
Hearing loops: Induction loops for hearing aid users
Older buses
Pre-PSVAR buses (step-entrance, no wheelchair access) are now mostly withdrawn from regular service. You might still see them on heritage routes, private hire, or in preservation.
BusOva tip
When photographing buses, a shot of the entrance area can help show accessibility features. If you're adding an older or heritage vehicle, note whether it has step-entrance or low-floor access.
