How Rainy Weather Led to a Jackknife Accident on WA I-205

A jack-knifed tractor trailer caused a delay on a popular Washington highway.

The Disabled Tractor-Trailer Blocked ALL Lanes of the Roadway

WSDOT crews used a push-bumper truck to move the trailer and get the roadway open.

While an official cause wasn't given, the incident most likely was because of the rain. Slick conditions can cause the trailer to lose traction. When the trailer wheels lose traction, the trailer can slide sideways. If the driver suddenly brakes or turns sharp, the trailer can fold in toward the cab, causing the rig to jackknife.

The Most Common Causes of Jack-Knife Accidents are Due to:

• Sudden or improper braking
• Poor road conditions/slick ice or rain
• Speeding and/or sharp turns
• Mechanical Failure
• Improper cargo loading
• Driver error and fatigue

Jackknife accidents are one of the most catastrophic. When a big rig jackknifes, the trailer can swing out and collide with other vehicles. Fortunately, this was NOT the case in this incident.

LOOK: See how much gasoline cost the year you started driving

To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.

Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.
