Blind Spot Radar
for Trucks.
BLIS combines side BSIS and front MOIS radar to detect cyclists and pedestrians in the blind spots your mirrors can’t reach, helping New Zealand and Australian fleets protect vulnerable road users.
A blind spot radar built to protect the people around your trucks
BLIS is a 77GHz blind spot radar for trucks and heavy vehicles that detects vulnerable road users (cyclists and pedestrians) in a vehicle’s side and front blind spots and warns the driver in real time. It pairs two side BSIS (Blind Spot Information System) radars with a front MOIS (Moving Off Information System) radar, so one integrated kit covers the danger zones where most truck-versus-cyclist and truck-versus-pedestrian incidents happen.
Unlike a camera, radar sees in darkness, glare, rain, fog and dust, and it works whether a person is moving or standing still. For fleets across New Zealand and Australia operating in busy urban streets, work sites and tight depots, that means fewer near-misses, calmer drivers and a clear step toward modern heavy-vehicle safety standards.
Why truck blind spots are so dangerous
A loaded truck or bus has blind spots running down both sides and directly in front of the cab. A cyclist alongside the kerb or a pedestrian stepping off it can disappear from the driver’s view entirely, exactly when the vehicle is turning or moving off from rest.
Turning & moving off
Low-speed left turns and pulling away from lights are the highest-risk moments for cyclists and pedestrians around heavy vehicles.
Mirrors aren’t enough
Extra mirrors help, but they still leave gaps. Radar covers the whole side and front zone continuously, without the driver having to look in three places at once.
Shared urban roads
As cycling and walking grow in NZ and Australian cities, trucks increasingly share tight space with vulnerable road users.
Two systems, one layer of protection
BLIS uses three radar sensors and a single in-cab display. The two side radars handle blind-spot information (BSIS); the front radar handles moving-off information (MOIS). Together they give the driver an early information signal and, when a collision becomes likely, a clear warning signal.
BSIS: side blind-spot detection
Two side-mounted radars monitor the full length of the vehicle’s side blind spots, giving up to 180° of coverage. They pick up cyclists overtaking or waiting alongside and warn the driver, escalating to a collision warning when the indicator is engaged toward that side.
- Covers both flanks, front to rear of the vehicle
- Detects moving and stationary road users
- Ties into the turn signals for turn-aware warnings
MOIS: front moving-off detection
A single front-mounted radar watches the area directly in front of the cab. During start-off and low-speed manoeuvres it warns of a person ahead, such as a cyclist stopped at a junction or a pedestrian on a crossing the driver simply can’t see over the bonnet.
- Protects the high-risk moment of pulling away from rest
- Shows distance to the nearest person and flashes a warning when very close
- Switches off automatically at higher speed and resumes for the next stop
Why fleets choose BLIS
It’s not just about ticking a box. A blind spot radar that drivers trust changes how confidently and safely your trucks move through busy areas.
See what mirrors can’t
Up to 180° of side coverage plus the front zone, with continuous monitoring of the spots a driver physically cannot see.
Protect cyclists & pedestrians
Purpose-built to detect vulnerable road users (moving or stationary) and alert the driver before a turn or move-off becomes a collision.
Speed-adaptive alerts
The system adjusts its warning logic from standstill through to highway speed, so drivers get relevant alerts, not constant nuisance beeps.
All-weather, day or night
77GHz radar isn’t fooled by darkness, sun strike, rain, fog or dust the way cameras can be, for reliable detection in real conditions.
Fewer incidents & claims
Catching near-misses early helps reduce collisions, downtime, insurance exposure and the human cost of a serious crash.
Built around UN R151 & R159
Engineered to recognised BSIS and MOIS standards, helping fleets get ahead of evolving heavy-vehicle safety expectations.
Clear warnings the driver actually understands
A single in-cab tracking display shows what’s happening on each side and in front, backed by an adjustable buzzer. The closer and more urgent the risk, the stronger the alert.
Detection that adapts to speed
BLIS changes how it warns based on what the truck is doing, focusing on close-in turning risks at low speed and lane-change risks at higher speed, so alerts stay meaningful.
- Stopped & moving off: watches for people entering the side and front zones, and flags anyone dangerously close.
- Low speed / turning: escalates to a collision warning when a road user is alongside and the indicator is on toward them.
- Higher speed: blind-spot and lane-change logic for vehicles and riders moving up the side of the truck.

Aligned with modern heavy-vehicle safety standards
BLIS is engineered around the two international regulations written specifically to protect vulnerable road users around heavy vehicles.
UN R151: BSIS
The Blind Spot Information System regulation covers detection of cyclists down the side of a vehicle and applies to vehicle categories M2, M3, N2 and N3.
UN R159: MOIS
The Moving Off Information System regulation covers detection of pedestrians and cyclists directly in front of a vehicle as it moves off from rest.
