1. The Four Blind Zones, Mapped
Right side: the cyclist and pedestrian zone that turns right turns into the deadliest truck maneuver in urban fleets. Immediate front: the hood-length gap that hides crossing traffic. Rear: everything behind a 7-meter box. Left mirror gap: the overtaking vehicle that disappears between mirror views. Mirrors cover fragments of these; a 4-camera system covers all four completely, on one screen the driver glances at like a mirror.
- Right: cyclist/pedestrian turn zone
- Front: hood-length blind gap
- Rear: box and trailer view
- Left: the mirror overlap gap
2. The Camera-to-Zone Layout
The TM4 layout maps one camera per zone: road-front high, rear above the box, right-side at the step or mirror arm, and left-side or cabin per operations. Quad view puts all four on the 10-inch monitor; the right-side camera can be assigned to auto-display on left-turn indicators on supported configurations. The driver's scan pattern stays unchanged — the screen replaces what mirrors cannot show.
- Front high: road + crossing traffic
- Rear: box + trailer coverage
- Right: the turn-zone camera
- Quad view: one glance, four zones
3. The Cyclist-Side Turn: The Liability Case
Urban fleets name the right-turn cyclist incident as their highest-severity claim — in fault, in settlement and in reputation. A right-side camera recording continuously turns the maneuver into documented fact: the clip shows the cyclist's approach, the truck's position and the turn timing. Fleets report the camera changes driver behavior immediately — the recording driver checks the screen before the turn because it shows more than the mirror.
- Right-turn cyclist claims: documented
- Continuous recording, not just live view
- Driver behavior shifts immediately
4. Night and Weather: When Blind Zones Get Darker
Blind zones are hardest at night and in rain — exactly when mirrors fail. Full-color night vision on all four cameras keeps zones visible under urban lighting and beyond it, and washdown-rated housings keep the lenses working through winter salt and pressure washing. Camera placement high enough to avoid spray, with weekly lens checks, preserves the night advantage.
- Full-color night vision ×4
- Urban lighting + beyond coverage
- Washdown-rated for winter
5. The Fleet Rollout Logic
Safety managers standardize the rollout: one TM4 kit per vehicle, identical camera positions across the fleet (drivers switch trucks without relearning), recording as the insurance evidence layer, and commissioning checklists per vehicle. Insurance conversations start with the footage library — fleets report the camera list opening premium discussions. Kits ship 12/24V, MOQ 1 pc, dealer installation support included.
