What should you do if you get hung up on railroad tracks?
Get out of the vehicle and away from the tracks. Check signposts or signal housing at the crossing for emergency notification information. Call 911 or other emergency number.
Get out of the cab and walk up the tracks about 1,000 ft to warn any oncoming train of the hazard. Call 911 asap.
Immediately call 911 before getting out of the cab if you have time. Give them your location. Get out of the truck and wait for help to arrive. Try to warn any oncoming trains.
Immediately disconnect from the trailer and pull the tractor safely away from the tracks. Call 911. Allow a tow truck to safely remove the trailer from the tracks.
If for any reason you get stuck on the tracks, get out of the vehicle and away from the tracks. Check signposts or signal housing at the crossing for emergency notification information. Call 911 or other emergency number. Give the location of the crossing using all identifiable landmarks, especially the DOT number, if posted.
If you get stuck on the tracks, get away from the truck and the tracks asap! Simple as that. Get out of there. Then call 911.
When a combination vehicle makes a low-speed turn - for example a 90-degree turn at an intersection - the wheels of the rearmost trailer axle follow a path several feet inside the path of the tractor steering axle. This is called low-speed offtracking. Excessive low-speed offtracking may make it necessary for the driver to swing wide into adjacent lanes to execute the turn (that is, to avoid climbing the inside curbs or striking fixed objects like telephone poles).
This performance attribute is affected primarily by the distance from the trailer kingpin to the center of the trailer rear axle, otherwise known as the wheelbase of the semitrailer. To prevent trucks from being too long to maneuvering safely around turns encountered in cities and towns, the maximum length allowed from the kingpin to the trailer tandems is set by the individual states.
Even if you are not aware of being drowsy, if you have a sleep debt you are still at risk. Here are a few ways to tell if you are about to fall asleep. If you experience any of these danger signs, take them as a warning that you could fall asleep without meaning to.
Your eyes close or go out of focus by themselves.
You have trouble keeping your head up.
You cannot stop yawning.
You have wandering, disconnected thoughts.
You do not remember driving the last few miles.
You drift between lanes, tailgate or miss traffic signs.
You keep jerking the truck back into the lane.
You have drifted off the road and narrowly missed crashing.
Wet roads can always be slippery, but one of the following conditions tends to be the most dangerous. Which one?
Right after it starts to rain, the water mixes with oil left on the road by vehicles. This makes the road very slippery. If the rain continues, it will wash the oil away.
After it finishes raining and the roads begin to dry, the wet patches are far more slippery because they form on blemishes in the road
After it has been raining for a while the roads become extra slick because the water has worked its way into the porous asphalt
The inside lanes of a four-lane highway are the slickest after the rain stops because they see less traffic
Just After Rain Begins. Right after it starts to rain, the water mixes with oil left on the road by vehicles. This makes the road very slippery. If the rain continues, it will wash the oil away.
Most people aren't aware of this phenomenon. As soon as it starts raining, that road becomes slick!

Tips For Passing the Commercial Driver's License (CDL) Permit Test
Practice Makes Perfect: The best way to both mentally and physically prepare for the written exam is to take practice tests. Start out with open-book tests and gradually work your way up to giving yourself a time limit. Finally, before the big day, take a practice exam as if it were the real thing without any help. This will give you a good indication of how well you understand the material.
Understand Instead of Memorize: Memorizing information can be helpful for the written exam, but the key to being fully prepared is to understand the material rather than just memorizing it. Understanding the material will allow you to answer questions correctly no matter how they are worded.
Real World Applications: When struggling to understand concepts, create real-world scenarios to make the information more relevant to your life. Doing this will make it easier to remember come test time.
Utilize Study Strategies: Utilizing study strategies such as flashcards, songs, rhymes, and phrases can help you remember the material.
Be Fresh and Alert: The night before the exam, get a good night's sleep and eat a filling breakfast on the morning of the exam. This will ensure you are fresh and alert to take your exam.
Begin Early and Space out Your Studying: It is important to give yourself ample time before the exam to get familiar with the material and get your mind ready for the big day. Consider taking a training course online or in-person, if it's required. Shop around for a course that works best for you.
By following these tips, you will be well prepared for your written CDL exam and on your way to a successful career.
