In the commercial transport sector, safety is a top priority—not only to protect drivers and the public, but also to reduce downtime, insurance costs, and reputational risk. Despite the increasing sophistication of modern trucks, certain parts of the vehicle remain consistently vulnerable to accidents. By understanding where these risks lie, fleet operators and transport managers can take more targeted steps to reduce incidents and improve safety.
1. Blind spots
Blind spots remain one of the most critical safety challenges for truck drivers. These are areas where visibility is limited or non-existent—typically along the nearside, offside rear, directly behind the trailer, and right in front of the cab.
Cyclists, pedestrians, and smaller vehicles can easily go unnoticed in these zones, especially during manoeuvres or lane changes. While most fleets now use wide-angle mirrors and blind spot detection systems, regular driver training and awareness are still essential.
2. Rear-end vulnerability
In addition to being a blind spot, the rear of the truck is particularly prone to being struck by following vehicles. This is often due to HGVs having longer stopping distances and slower acceleration—not because of poor visibility from the driver’s seat.
Rear-end collisions are common on motorways and dual carriageways, especially in heavy traffic or when other drivers misjudge braking distances. Fitting high-visibility markings, underrun protection bars, and working brake lights is crucial, along with promoting safe following distances for all road users.
3. Front end and cab area
The front of the truck, although benefiting from direct visibility, is highly vulnerable during frontal collisions—whether from oncoming traffic or lane departure incidents.
Damage to the cab can have serious consequences for both the truck driver and others involved. Many fleets now use forward collision warning systems and automatic emergency braking (AEB) as standard. However, these tools should support—not replace—driver attentiveness.
4. Tyres and underrun protection
Tyre blowouts are a leading cause of loss-of-control incidents, especially at higher speeds. Low tyre pressure, wear and tear, or poor road conditions are often to blame.
Meanwhile, the underside of the vehicle—including axles, suspension, and braking systems—is also at risk of failure or damage without routine checks. Preventive maintenance, daily pre-use inspections, and compliance with DVSA standards are vital for minimising risk.
5. Trailer dynamics: off-tracking and tail swing
Turning dynamics introduce two major hazards: off-tracking and tail swing.
- Off-tracking happens when a trailer’s rear wheels cut a tighter path than the tractor unit during turns, which can lead to kerb strikes or entering adjacent lanes.
- Tail swing occurs when the rear overhang of the trailer swings outwards in the opposite direction of a turn. This can strike other vehicles, street furniture, or pedestrians.
Both issues are common in urban areas, on roundabouts, or during tight delivery manoeuvres. Solutions include advanced stability and sensor systems, driver training, and giving vehicles enough space to operate safely.
Conclusion
Accidents involving trucks are rarely caused by a single issue. But by identifying the most accident-prone areas of a vehicle, fleet operators can take a more proactive and strategic approach to safety.
From technology to training, investing in prevention not only protects lives—it also reduces costs, boosts compliance, and safeguards your business reputation.
