Performing pre-trip inspections ensures successful and on-time cargo delivery, enabling drivers to stay on their employer’s schedule.

Improved Safety of Passengers and Other Road Users

Regular pre-trip and post-trip inspections are crucial for ensuring the safety of passengers and other road users. These inspections help to catch potential issues with the truck before it undergoes another long journey. 

Companies often require two drivers to complete these inspections to ensure that the vehicle is safe to go out on the next trip. Post-trip inspections are also mandatory and critical in ensuring that vehicles are safe on the road. Failure to conduct these inspections or address known defects can increase liability, even if drivers are not at fault for any accidents that may occur. 

Truck accidents may represent a small portion of overall vehicle accidents but consider the following statistic:

For every 100 million miles driven on American roads, large truck crashes lead to approximately two fatalities and cause injuries to over 60 people

By conducting pre-trip and post-trip inspections, drivers and fleet managers can help mitigate potential liability and protect themselves and other motorists on the road.

Reduced Accidents and Hazards

Pre-trip and post-trip inspections are essential to ensure the safety of everyone on the road. Regular inspections can help to identify potential hazards and prevent accidents caused by equipment failure. 

Conducting thorough inspections can mitigate liability, minimize over-the-road breakdowns, and prevent out-of-service violations. By using a disciplined step-by-step approach and following a comprehensive checklist, drivers can catch any potential issues before they become catastrophic. 

Ensuring drivers perform required inspections can significantly reduce accidents and protect the bottom line.

In conclusion, pre-and post-trip inspections are essential for minimizing breakdowns and preventing out-of-service violations. By following the dos and don’ts list, you can ensure that your inspections are done correctly.

FAQ
