Hard Acceleration

Harsh or hard acceleration occurs when a driver uses more power than necessary to pull off from a dead stop. This action can indicate distracted or aggressive driving which leads to increased tire wear, a variety of maintenance issues, and sometimes, costly insurance claims.

Overview

Fleet vehicles fitted with telematics hardware can detect an increase in speed greater than 8.35-9.65 MPH per second and trigger a harsh acceleration alert. This figure depends upon the class of vehicle.

  • Harsh acceleration is a common result of drivers not paying attention to the pace of traffic and needing to speed away from a stop line.
  • It can also be because a driver is so distracted that he doesn’t notice that he’s on a collision path with another vehicle, person, or object, necessitating aggressive action to prevent a serious accident or injury.

Effects of harsh acceleration

  • Hard acceleration often makes harsh braking a necessity
  • Harsh accelerations burn more fuel which is bad for the environment
  • Risk of injury to drivers, passengers, and pedestrians
  • Risk of damage to other vehicles, public property, or valuable loads
  • Increases vehicle maintenance costs
  • Can necessitate vehicle downtime
  • Contributes to fuel spend and wastage
  • Affects your bottom line

The Motive thresholds for hard acceleration are as follows: 

Light: 0.44G/9.65 mph/s
Medium: 0.41G/8.99 mph/s
Heavy: 0.38G/8.34 mph/s
