An 80,000-pound truck cannot stop, turn, or react like a passenger vehicle. One wrong move on the highway can change someone’s life forever.
Every day, Oklahoma drivers share highways and city streets with commercial trucks, tractor-trailers, and 18-wheelers. These vehicles are essential to transporting goods across the country, but their enormous size and weight create serious risks when accidents occur.
Whether you’re traveling on I-35 through Oklahoma City, I-44 near Tulsa, or a rural Oklahoma highway, understanding how to safely drive around semi-trucks could help prevent a devastating collision.
According to the Federal Motor Carrier Safety Administration (FMCSA), large trucks have significant blind spots, require longer stopping distances, and need more space to maneuver than ordinary passenger vehicles. In certain highway conditions, a large truck may need the length of up to two football fields to stop safely.
Here are seven ways to reduce your risk of being involved in a commercial truck accident.
One of the most dangerous places to drive is directly alongside a commercial truck. An 18-wheeler has large blind spots on all four sides, including areas directly behind the trailer and near the cab.
Many drivers assume that because they can see a truck, the truck driver can see them. Unfortunately, that is not always true.
The FMCSA advises motorists to avoid remaining in these blind spots and to use the truck driver’s side mirrors as a visibility reference. If you cannot see the driver in the mirror, you should assume they cannot see you.
What you can do:
Avoid driving directly beside a semi-truck for extended periods.
Never assume a truck driver knows you’re there.
Stay visible when approaching trucks at intersections or while merging.
Move ahead or fall back safely rather than remaining in a blind spot.
A fully loaded tractor-trailer can legally weigh up to 80,000 pounds under the general federal Interstate weight limit. That amount of weight makes stopping significantly more difficult than stopping an ordinary passenger vehicle. When a driver suddenly cuts in front of a truck, the truck driver may not have enough time or distance to respond, even when paying attention and following traffic laws. The FMCSA warns that a large truck traveling at highway speeds can require up to two football fields of stopping distance, depending on conditions. Before merging in front of a semi-truck, make sure you can see the entire truck in your rearview mirror and leave additional distance.
Remember: The space between your vehicle and an approaching truck is not necessarily enough space for that truck to stop in an emergency.
Passing an 18-wheeler requires more caution than passing another passenger vehicle. Because commercial trucks are much longer than cars, drivers need additional time and distance to complete a safe pass. Remaining beside a tractor-trailer unnecessarily increases your exposure to its blind spots. Whenever possible, pass on the left, use your turn signal, maintain a safe and legal speed, and leave plenty of room before returning to your lane. Avoid passing a truck when approaching steep downhill grades, intersections, or other areas where the truck may need to change speed or direction.
The FMCSA specifically recommends using the left lane when safely passing and avoiding lingering alongside commercial vehicles.
Have you ever seen a semi-truck move left before turning right?That movement is sometimes necessary because large commercial vehicles require more space to maneuver through intersections and around corners. Unfortunately, other drivers may misunderstand this movement and attempt to pass on the inside of the turn.This can place a passenger vehicle directly in the truck’s path.
This is particularly important on city streets, at busy intersections, and near highway exits.
Following too closely behind an 18-wheeler is dangerous for several reasons. First, you may have a limited view of the road ahead. You might not see stopped traffic, debris, or changing road conditions until the truck suddenly slows down. Second, large commercial trucks sit much higher off the ground than passenger vehicles. In certain rear-end collisions, smaller vehicles can travel underneath a truck’s trailer, potentially causing devastating injuries. Give yourself enough space to react to changing traffic conditions, avoid tailgating, and increase your distance in poor weather or heavy traffic.
Federal safety guidance also warns drivers about the risks of following commercial vehicles too closely, particularly when traffic stops unexpectedly.
Rain, snow, ice, high winds, and reduced visibility can make commercial truck accidents even more dangerous.
Large trucks already require significant stopping distances. Slippery roads and poor visibility can increase those challenges. Motorists frequently encounter changing weather conditions, making defensive driving especially important. When traveling near a tractor-trailer during severe weather:
Reduce your speed according to road conditions.
Increase your following distance.
Avoid abrupt lane changes.
Give trucks additional room to maneuver.
Never attempt to race past a truck in hazardous conditions.
Even experienced commercial drivers can encounter dangerous road conditions. Giving everyone additional room to react can help reduce the risk of a collision.
Distracted driving is dangerous around any vehicle, but the consequences can be especially severe when an 18-wheeler is involved. A truck driver may be preparing to change lanes, slowing for traffic, or navigating a difficult turn. Passenger vehicle drivers need to stay alert and anticipate these movements.
The U.S. Department of Transportation emphasizes that patience, attention, and understanding the limitations of large commercial vehicles are important components of sharing the road safely.
Defensive driving can reduce the risk of an accident, but it cannot prevent every collision. Commercial truck drivers and trucking companies have legal responsibilities to operate their vehicles safely. When those responsibilities are ignored, the consequences can be catastrophic. Truck accident investigations may involve questions about driver fatigue, distracted driving, speeding, improper maintenance, unsafe cargo loading, or violations of federal commercial motor vehicle regulations. Unlike an ordinary passenger vehicle accident, a commercial truck accident may involve multiple responsible parties, extensive electronic evidence, federal safety regulations, and commercial insurance policies. Victims may face permanent disabilities, traumatic brain injuries, spinal cord injuries, extensive medical expenses, lost income, or the wrongful death of a loved one.
No amount of defensive driving excuses negligence by a commercial truck driver or trucking company.
