Mandatory alcohol testing for truck and bus drivers reduces alcohol involvement in fatal crashes

A study of nearly 70,000 motor carrier drivers and over 83,000 non-motor-carrier drivers found that mandatory alcohol testing programs reduced alcohol involvement in fatal crashes by 23%. The study's findings suggest that implementation of such programs can improve safety records in the US and other countries.

Optimal trip and load planning

The Efficient Load project aims to harmonize capacity utilization and trip planning in a single step, significantly improving truck use and reducing energy costs. The new system is expected to reduce ton-kilometers by 15-20% and integrate seamlessly with existing software.

Obesity linked to dangerous sleep apnea in truck drivers

A new study confirms obesity-driven testing strategies can identify commercial truck drivers with high likelihood of obstructive sleep apnea, suggesting mandatory screenings could reduce truck crashes. The study also highlights the need for prohibition of 'doctor shopping' to ensure drivers receive treatment.

Transporting broiler chickens could spread antibiotic-resistant organisms

Researchers found increased levels of pathogenic bacteria on surfaces and in the air inside cars behind trucks carrying broiler chickens. The study, published in the Journal of Infection and Public Health, suggests a real exposure potential for antibiotic-resistant organisms, particularly during summer months when windows are open.

Coal and black liquor can produce energy from papermaking

A team of Penn State engineers discovered that combining coal with papermaking black liquor waste creates a synthesis gas that can be converted into DME, a clean-burning fuel. This process reduces the carbon footprint of traditional coal-to-liquid processes and offers a more efficient alternative to burning black liquor for heat.

Penn researchers find many commercial drivers have impaired performance due to lack of sleep

A study by Penn researchers found that truck drivers who get too little sleep or suffer from sleep apnea show signs of fatigue and impaired performance. The study examined 406 truck drivers and found that those with severe sleep apnea had performance impairment similar to that of drivers who are legally drunk.

Study reveals sleepiness and performance impairment in commercial drivers

A study of 340 drivers found that chronic short sleep duration and severe sleep apnea increase the risk of sleepiness, performance impairment, and decreased task vigilance while driving. The researchers suggest that the Federal Motor Carrier Safety Administration should implement plans to identify and treat sleep-impaired drivers.

Risk higher for truckers in eleventh hour

A recent Penn State study suggests that increasing the truck driver's hours of service beyond 10 hours leads to a significant rise in the risk of crashes. The most concerning increase occurs within the 9th, 10th, and 11th hours of driving.

Flying low-drag trucks: aerodynamic concepts & controls developed for aircraft will cut fuel use, improve control, in tractor-trailers

Researchers at Georgia Tech have applied aerodynamic concepts from aircraft to tractor-trailers, reducing drag by up to 50% and improving directional control, traction, and braking. The Circulation Control system uses compressed air to create lift and reduce rolling resistance, with potential fuel savings of up to 12%.

Snowmobile Injuries

Alaska's snowmobiles carry higher injury death rates than on-road motor vehicles, with factors like alcohol intoxication, lack of helmets, and trail limitations contributing to the high risk.
