5 Truck Safety Features That Can Help Prevent Accidents
22 May 2026
Modern commercial trucks are built with multiple safety systems designed to reduce the risk of crashes on the road. These features do not eliminate all accidents, but they significantly lower the chances of serious collisions when working correctly.
Salt Lake City sits along a major freight corridor, with Interstate 15 and Interstate 80 serving as primary routes for heavy commercial traffic throughout the region. Utah's mountainous terrain and winter road conditions make truck safety technology especially critical in this area.
If you were hurt in a crash despite these systems being in place, speaking with a Salt Lake City truck accident attorney can help you understand your options.
1. Automatic Emergency Braking (AEB)
AEB uses sensors and cameras to detect obstacles and apply brakes automatically when a driver fails to react in time. The FMCSA has proposed requiring AEB on new heavy vehicles, and studies show it can reduce rear-end truck crashes by up to 40 percent.
How It Helps
- Scans the road ahead continuously, even without driver input
- Applies full braking force if the driver does not respond in time
- Reduces crash severity even when it cannot prevent the impact fully
Where It Falls Short
- Older trucks may lack AEB or carry outdated sensor versions.
- Poor maintenance can delay or prevent system activation
- Does not compensate for excessive speed or aggressive tailgating
2. Electronic Stability Control (ESC)
ESC monitors truck movement and adjusts braking and engine power to prevent rollovers and jackknifing accidents. Under 49 CFR 571.136, ESC is federally required on certain classes of heavy vehicles.
What It Corrects
- Oversteer and understeer that cause trailers to swing out of control.
- Sudden load shifts during sharp turns or emergency maneuvers.
- Loss of traction on wet, icy, or uneven road surfaces.
Its Limitations
- Cannot prevent rollover if the truck is traveling far above a safe curve speed.
- Improper cargo loading reduces how effectively the system responds.
- Requires regular sensor calibration to function correctly.
3. Lane Departure Warning Systems
These systems detect when a truck drifts out of its lane without a turn signal and alert the driver through sound, vibration, or a dashboard display.
- Most effective on highways with clearly painted lane markings.
- Faded or missing road markings reduce detection accuracy.
- Some systems pair warnings with active steering correction.
- Drivers who repeatedly disable alerts increase liability risk for their carrier.
4. Blind Spot Detection
Commercial trucks have large blind zones on all four sides, making nearby passenger vehicles difficult to see. Radar sensors alert the driver when another vehicle enters a zone the mirrors cannot cover.
- Sensors cover the widest blind zones along the sides and rear of the trailer.
- Audible and visual alerts activate before a lane change becomes dangerous.
- Some systems include live camera feeds displayed on the dashboard.
- The FMCSA's Large Truck Crash Causation Study linked blind spot errors to a significant share of truck crashes.
5. Event Data Recorders (EDR)
EDRs store data on speed, braking, steering input, and engine performance in the moments before a crash. Under 49 CFR Part 390, carriers are required to retain certain vehicle operation records.
- Data captured by EDRs can confirm whether a driver was speeding or braking properly.
- Records are often used in legal investigations following serious truck accidents.
- Carriers are legally obligated to preserve this data once a crash occurs.
- Tampering with or destroying EDR data after an accident can result in serious legal consequences.
Key Takeaways
- AEB, ESC, and lane departure systems address the most common causes of serious truck crashes.
- Federal regulations under 49 CFR require certain safety systems on commercial vehicles.
- Safety technology supports driver performance but does not replace the legal duty of care
- Blind spot detection and EDRs play a direct role in both crash prevention and post-crash accountability.
- Malfunctioning or disabled safety features can strengthen a negligence claim after an accident.
- EDR data is legally protected after a crash and must be preserved by the carrier.
