A semi-trailer swings across lanes and traffic stops suddenly. A jackknife truck accident can involve the truck, several passenger cars and more than one collision sequence. If you were injured, a useful first step after medical care is preserving the facts before vehicles and electronic records move on.<\/p>\n
There is no single cause. Braking, speed, roadway conditions, equipment, loading and other drivers’ actions may all be investigated. A jackknife by itself does not prove a trucking company or driver was negligent. Crash reconstruction needs the physical scene, witness accounts and available vehicle data.<\/p>\n
Record the truck and trailer identifiers, carrier name, license plates if safely visible, crash location, weather, lane positions, witness details and report number. Keep your photographs, dashcam file, medical records, repair estimates and towing receipts. For CHP-investigated collisions, review the agency’s report-request process<\/a>. Commercial records may require prompt preservation requests by counsel.<\/p>\n An attorney may assess the driver’s actions, maintenance and inspection records, cargo information, electronic data, other drivers’ roles and multiple insurance policies. The FMCSA tracks jackknife involvement in truck crashes<\/a>, but statistics cannot decide an individual case.<\/p>\n See our truck accident practice<\/a>, freeway accident page<\/a> and semi-truck impact guide<\/a>.
