Combatting Driver Fatigue
Driving a Class 8 truck is a demanding job, but advancements in driver-assist technologies, improved vehicle design and better in-cab comfort solutions are making it easier for drivers to stay alert and comfortable behind the wheel and get better rest in their sleeper.
“A lot of the driver-assist technologies are really important and can help take some of the stress off of a driver,” said Chuck Pagesy, director of safety for Penske Truck Leasing.
Driver-Assist Technologies
Power steering, disc brakes and automatic transmissions have made driving less physically demanding while improving the overall driving experience. "With automatic transmissions, you're not pushing the clutch in, and you're not having to move over and shift. That saves a lot of effort from the drivers,” Pagesy said, adding that most trucks today have automatic transmissions, which also helps improve fuel economy.
Today's steering systems have active pull compensation and active steering damping, which can enhance vehicle stability, improve handling characteristics, and provide better steering feel and control for the driver. Blind spot monitoring and backup cameras also make driving a little easier as well as safer.
Several driver-assist technologies can take corrective action that can aid fatigued drivers. “With lane departure, if drivers start going off course, it will pull the vehicle back into the lane,” Pagesy said. “Smart cruise control will adjust the speed and apply automatic braking if drivers are overtaking the vehicle in front of them too fast.”
However, Pagesy said drowsy drivers shouldn't rely on technology to protect them if they're tired and must always put safety first by resting as needed.
In-Cab Comfort
New innovations in late-model equipment are also addressing driver fatigue. "Ergonomics in the last ten years have advanced. The steering wheel is smaller. The controls are within hands reach,” Pagesy said. “Some trucks have heated seats, air-conditioned seats and vibrating seats. All of these elements can make the driver more comfortable and help the driver reduce fatigue.”
OEMs have implemented many creature comforts from passenger cars into commercial motor vehicles, but fleets typically have to spec them separately. “A lot of your more progressive carriers that are trying to improve safety and retain drivers will invest in them,” Pagesy added.
Quality Rest
While many long-haul drivers are used to the sound of idling while resting, auxiliary power units (APUs) provide good climate control without the need to idle, which also saves fuel and minimizes wear and tear on the engine. “Some of our customers specify gel mattresses or foam core mattresses with foam that adjusts based on the body heat,” Pagesy said.
APUs can also power electrical appliances, including CPAP machines used to treat sleep apnea or comfort items that make rest periods more enjoyable, like entertainment systems or microwaves.
Quick Tips for Better Sleep on the Road
Quality sleep is essential for staying alert and focused while driving. Here are some practical tips to help improve their sleep quality:- Aim for a consistent sleep schedule: Try to go to bed and wake up at the same time each day, when possible.
- Block out light and noise: Use blackout curtains and white noise machines or earplugs to minimize disruptions.
- Ensure a cool sleeping environment: Maintain a comfortable temperature in the cab, ideally between 60 to 68 degrees Fahrenheit, to facilitate restful sleep.
- Avoid stimulants before bed: Reduce caffeine and screen time at least an hour before sleeping.
- Invest in a quality mattress and pillow: Creating a comfortable sleeping setup can significantly improve the quality of rest.
- Develop a pre-sleep routine: Try to engage in relaxing activities before bed, such as reading or listening to music, to signal your body it's time to sleep.
