Petaluma Bike Accidents with Big Rigs

The scores of big rigs traveling on our nation’s streets and highways pose a problem for cyclists because of the size and weight difference. A fully loaded big rig can weigh as much as 80,000 lbs, which is 400 times heaver than the average bike and rider.

This means that even a small bump can be devastating to the cyclist. This fact was made apparent recently in Petaluma.

Petaluma Cyclist Killed in Collision with Big Rig

On Wednesday, October 13, 2019, around 12:20 p.m., a cyclist was hit from behind by a semi-truck at U.S. 101 on Lakeville Street. Police at the scene say that the cyclist and the truck were traveling in the same direction when the cyclist was struck.

The truck driver remained at the scene and cooperated, and police say that the accident is under further investigation. It’s unknown if alcohol or drugs were a factor in the accident. The cyclist was pronounced dead at the scene.

Dangers of Big Rigs to Bicycles

Because of the weight, height and overall size difference, a cyclist riding near a big rig has numerous risks.

  • Blind Spot: Also called no-zones, a big rig has numerous blind spots where a bicycle can easily fit. The truck driver is perched high in his or her seat, and a bicycle rider is comparatively low to the ground. This alone creates difficult. Then add the numerous natural no-zones, and it’s easy to see how a cyclist can be unseen to the driver.
  • Right Hook: When a cyclist is riding on the right-hand side of the right lane, or in a bike lane, motorists will often make a right turn and not see the cyclist to their right. A vigilent cyclist knows to look out for a right hook. The large big rigs will veer a bit left before making a right turn so their rear wheels will clear the curb. Many cyclists see the rig veer to the left and move into the newly open space only to be crushed by the truck as it turns right.
  • Left Cross: Just as deadly as the right hook, the left cross happens when a big rig takes a right-hand turn onto another street, and the cyclist trails behind the truck dutifully waiting for it to turn before it speeds on through the intersection. However, the truck can block the vision of the driver and an oncoming vehicle turning left into the path of the cyclist.

The bottom line is that trucks are huge, cyclist are not. A savvy cyclist doesn’t ride near a big rig, rather it slows down and puts a bit of distance between itself and the truck. The longer the cyclist rides close to the truck, the more likely an accident is.

Big Rig Bicycle Crash Injuries

An impact with a large truck is enough of a challenge to a cyclist, however, in almost every accident, the rider is ejected from the bike and hits the pavement in a second impact. Because of this, certain common injures happen in these crashes.

  • Traumatic Brain Injuries
  • Severe Concussions
  • Wrist Fractures
  • Broken Arms/Legs
  • Chest Compression
  • Internal Injuries/Bleeding
  • Severe Road Rash
