Jackknifing Can Stop Everything in Its Tracks
A jackknifed rig puts lives at risk and locks up traffic fast. When the trailer swings out and folds against the cab, the driver loses control of a vehicle that can easily weigh over 80,000 pounds. These events often start small but escalate quickly. Our tow truck team has been on many San Antonio semi towing calls where one mistake led to hours of cleanup and damage. It doesn’t take a major failure to trigger a jackknife, just the wrong move at the wrong time. That’s why prevention starts long before the wheels hit the highway. Understanding the most common causes and how to counter them is the first step to staying upright and on course.
Road Conditions Make or Break the Trip
Black ice, rain-slick roads, and loose gravel reduce traction and increase risk. If the trailer can’t grip the road, it only takes one misstep to throw everything off.
Rain affects more than the road surface. Visibility drops, stopping distances grow, and drivers have less time to react. In Texas, road conditions can shift in minutes. A dry road can flood in the time it takes to change lanes. If we don’t adjust our speed or give more space in bad weather, we’re inviting problems.
Here’s what helps:
- Avoid braking hard on curves or slopes.
- Use engine braking carefully when roads are wet.
- Reduce speed before downhill grades begin.
Panic Moves Make Things Worse
When something feels wrong behind the wheel, the worst move is to slam the brakes. Sudden braking locks the wheels and can send the trailer swinging out of line.
Once that trailer starts to swing, there’s little time to react. We’ve seen many San Antonio semi towing recoveries that started with one overreaction. A skid might seem minor at first, but it can spiral fast.
When handling skids:
- Ease off the gas.
- Brake lightly and steadily.
- Steer in the direction of the slide to regain control.
Poor Loading Can Set You Up to Fail
An overloaded or off-balance trailer is harder to control. Weight that shifts mid-turn or during braking can push a trailer into a bad angle. Unsecured freight creates serious hazards.
To reduce risk:
- Distribute weight evenly front to back and side to side.
- Make sure cargo is fully secured before moving.
- Double check loads before heading out, especially if you’re unfamiliar with the contents.
Balanced loads track straight. Unbalanced ones don’t give you a chance.
Traction and Braking Depend on Maintenance
Tires and brakes do more than just stop the truck. They help control the trailer. When tires are worn or brakes aren’t tuned, control goes out the window.
Plenty of rigs jackknife because the tread was gone or the braking system wasn’t balanced. Before hitting the road, we check:
- Tire pressure and condition.
- Brake strength and response.
- Suspension components for wear or looseness.
Assumptions don’t keep rigs on the road. Inspections do.
Skill Only Works When Focused
Years of experience behind the wheel won’t help if attention slips at the wrong time. Jackknifing doesn’t care about your driving record. San Antonio semi towing calls can come from seasoned vets and newer drivers alike. In many cases, distraction or fatigue can contribute to the problem.
What helps:
- Get rest. Fatigue reduces reaction time.
- Stay off your phone and avoid distractions.
- Watch for early trailer sway in your mirrors.
If you aren’t paying attention to the trailer, you won’t see the warning signs.
