Semi

Daimler believes that it's close to getting permission to begin testing semi-autonomous big rigs on the roads there very soon.

A mother and daughter survived the kind of crash you usually only see in action movies when their car slid under an 18-wheel semi truck Monday afternoon.

Motorists in England have one more way to worry about getting stopped by the police this spring. The cops are using an unmarked semi to look down on drivers and check for any offenses, like using a cell phone or texting.

The four occupants of a minivan in Michigan were in for a terrifying ride early in the morning on January 7. Their minivan got lodged under the back of a semi's trailer, and the vehicle was drug 16 miles along Interstate 75. During that time, the driver was on the phone with 911 but couldn't exactly say where the stricken van was because of the snowy conditions.

A Lotus F1 car and the truck in which it's transported may both be powered by Renault and share a common JPS livery, but as far as size and performance are concerned, they're at opposite ends of the spectrum. So if you had to jump one over the other, you'd think it'd be a no-brainer to skip the single-seater over the tractor-trailer. Right? Well that

Nobody should be shocked that a big, heavy vehicle like a semi truck takes a longer distance to stop than the average passenger car; it's just basic physics. However, this BMW X5 driver seemingly has a major problem grasping the concept, and it results in some serious damage to the back of his SUV.

A lot of drivers hate seeing semis on the freeway because of their intimidating size and slow speed, but big rigs are absolutely vital to moving goods around the country. The US is on the road to a major trucking crisis, though. A recent analysis from Business Insider finds that we aren't producing nearly enough new drivers to fill all the needed seats. By 2022, the shortfall could reach 239,000 people.

A new report into the crash that critically injured funnyman Tracy Morgan and killed comedian James McNair has revealed that the Peterbilt semi that caused the accident was traveling at 20 miles per hour over the speed limit. It's also alleged that the truck driver behind the wheel of the semi ignored construction signs and drops in t

Think 10 miles per gallon, and your mind may harken back to muscle cars along the line of the General Lee from The Dukes of Hazzard. Apply that figure to a semi-truck, though, and we're talking actual fuel-efficiency gains. That's what the four-year-old SuperTruck program shot for, and two of its four teams have already hit that goal.

With the debate about how to fund the US interstate system already raging, there may be another big highway controversy on the horizon. The US Department of Transportation might slow down some of the vehicles on the nation's roads by mandating speed governors on semi trucks.

So, it's a safe bet that the following video is the craziest thing you'll see all day. Maybe this week, and quite possibly, this month. It stars, in no particular order, a drifting Freightliner semi driven by Pikes Peak champ Mike Ryan, a dock worker/stuntman being pulled behind said semi, a Ford Crown Victoria driving on t

In his State Of The Union speech last week, President Obama made mention of higher fuel economy standards for big trucks. We all know (or should, at least), that picking up the low-mpg stragglers in our vehicle fleet is where we can

Roundabouts are generally a good idea when it comes to easing traffic flow, as they eliminate traffic lights by keeping cars moving more often. They are not, however, great if you're the driver of a semi with a particularly oversize load. Depending on the length of the trailer, in fact, a roundabout may be a wildly difficult obstacle, requirin

A person's portfolio of automotive experiences should contain more than just family vehicles and the occasional sports car. That's why our list of 1,001 Automotive Things To Do Before You Die includes driving all sorts of different vehicles. So far we've driven drift vehicles, off-roaders and even John Neff

Cummins and Peterbilt have created a new demonstration tractor trailer that boasts a 54-percent increase in fuel economy over current trucks. This particular Class 8 Peterbilt 587 uses a high-efficiency Cummins ISX15 engine and managed to average 9.9 miles per gallon over 11 runs over the 312-mile route between Fort Worth and Vernon

What in the world is the vehicle you see above? Well, um... yeah. We have no idea. According to the video description from YouTube, however, it's a modified Jeep Wrangler, and it comes from the same person who created the equally insane side-by-side merged Wrangler you saw here.

Navistar International's not beating 'em, so it looks like it's going to join 'em. The truckmaker, which has been pushing its exhaust-gas recirculation process as a cheaper, simpler emissions-treatment method than the selective catalytic reduction method used by its competitors, will likely switch to SCR to better appease the Environmental Protection Agency, the Wall Street Journal reported, citing people familiar with the process that weren't identified.

The news may be flooded with stories about the lagging U.S. economy and disappointing jobs reports, but it appears there is at least one profession that could use a few more applicants. USA Today reports that there is a genuine shortage of truck drivers, and the problem is leading to pricier deliveries and longer waits on packages.

Stability control was made mandatory on passenger vehicles for this current model year, but it's still not a requirement for semis and busses. But that could soon be changing, as the National Highway Traffic Safety Administration has proposed requiring the technology on all new large commer

A range of safety groups are calling for judicial review of federal rules for truck drivers' hours of service. According to a lawsuit filed by Advocates for Highway and Auto Safety, Public Citizen, the Truck Safety Coalition and two truck drivers, the new rule doesn't protect the public from tired truckers. The U.S. Department of Transportation's Federal Motor Carrier Safety Administration recently ruled drivers could only work 70 hours within a s
