CDL Tips for Sharing the Road with Four-Wheelers

There’s a lot of advice out there for four-wheelers on how they should conduct themselves around big rigs. Yet, at times it seems many just don’t get the memo. While it may be frustrating that you can’t control what others do on the road, you do have control over the situation. You can choose to stay calm and patient, recognize hazards early, and make safe driving decisions even if other drivers make mistakes. In fact, your predictable driving can reduce confusion and gives other motorists more time to react. Along those lines, here are some tips to keep yourself and others safe while sharing the road with four-wheelers. 

1. Expect Four-Wheelers to Make Mistakes

Many four-wheelers don't understand how commercial vehicles operate or how their actions affect you behind the wheel. Stay positive by not taking their mistakes personal. If you expect four-wheelers to cut you off, tailgate, linger in your blind spots, honk unnecessarily, brake suddenly, change lanes without signaling, and drive aggressively, then you can drive proactively. 

Rather than letting the poor decisions of others ruin your day, if you expect the unexpected it can help you stay calm, maintain a safe speed, and focus on preventing crashes—not "teaching another driver a lesson."  Defensive driving often means letting someone else's poor decision stay their mistake instead of becoming yours. 

2. Stay Focused

No matter how much your phone may seem to be calling your name or you’re feeling hungry behind the wheel, don’t let anything take your eyes and mind off of driving. It’s better to pull over and make a phone call or grab a bite than taking the risks associated with distracted driving. Staying focused allows you to keep your attention where it’s needs to be, on: traffic conditions, your mirrors, road signs, work zones, weather, pedestrians and cyclists, and other vehicles entering from ramps and intersections.

3. Watch Your Blind Spots Constantly

Commercial vehicles have much larger blind spots than four-wheelers. Remember you can stay in control by regularly checking and rechecking your mirrors especially before lane changes, signaling early before changing lanes, and being especially alert for motorcycles and small cars in your line of movement.

The FMCSA recommends checking your mirrors every 8 to 10 seconds while also scanning well ahead of your vehicle for developing hazards. This helps you identify vehicles entering your blind spots before changing lanes or making turns.

4. Leave Plenty of Following Distance

Professional drivers know that space equals safety. A fully loaded tractor-trailer requires much longer to stop than a passenger vehicle. Leaving adequate following distance gives you time to react if traffic suddenly slows.

The FMCSA recommends using a following distance based on vehicle length and increasing that distance in poor weather, heavy traffic, or reduced visibility.

5. Be Patient During Wide Turns

Many passenger vehicle drivers don't realize trucks need additional room to turn safely. Therefore, you can be proactive by signaling well in advance, positioning your vehicle properly, continuously monitoring your mirrors, watching for vehicles trying to squeeze between your truck and the curb, and completing the turn smoothly without rushing. Wide turns are a normal part of operating combination vehicles, and patience helps prevent crashes.

6. Expect Unsafe Merges

One of the most common hazards CDL drivers face is four-wheelers merging too closely in front of your truck.  When that happens, your goal is to recreate the space cushion—not to "hold your position." Here are some steps to follow when a car enters your safe cushion: 

1. Ease off the accelerator if needed.
2. Re-establish a safe following distance.
3. Avoid sudden braking whenever possible.
4. Continue scanning for additional hazards.
