Tie-Downs for Cargo

2 tie-downs are required for any load over 10 feet, minimum per load.

Nighttime Driving Lights

Use high beams whenever possible, dimming within 500 feet of other vehicles.

Proper Use of Horn

Holding Multiple CDLs

Only one CDL allowed at a time; must exchange out-of-state CDL when moving to Texas.

Medical Certification for CDL

Escape Ramps Functionality

Escape ramps become ineffective if traveling too fast; know their locations in advance.

Towing Vehicle Connection

Must not exceed 15 feet in length for safe towing connection.

Dual Tires and Blowouts

Stop immediately if noise resembles a blowout; handling may be compromised.

Fire in a Trailer

Keep trailer doors closed if a fire ignites; prevents spreading by limiting oxygen.

Must have appropriate markings (red flag at daytime, red light at night) if load extends over 4 feet.

Helper When Backing

Use a helper for safety due to blind spots; agree on hand signals prior.

Radiator Cap Safety

Check cargo security every 3 hours or 150 miles, and after breaks.

Dense Fog Driving Precautions

Recently repaved roads may alter vertical clearances; check signs carefully.

Tire Tread Depth Requirements

Front tires must have at least 4/32 inch tread depth; other tires need 2/32 inch.

Risks with Transporting Hanging Meat

Hanging carcasses can affect vehicle handling due to shifts in center of gravity.

Safe Braking on Steep Grades

Brake gently to 5 mph below a safe speed and let speed increase before repeating.

Identifying Antilock Braking System (ABS)

Look for sensor wires, a manufacturing date after March 1998, or an ABS light indicator.

Emergency Off-Road Driving

Keep one set of wheels on pavement, avoid sudden braking, and let the vehicle slow down naturally.

Convex Mirror Viewing

Objects appear smaller and farther away in convex mirrors; use caution when judging distance.

Increased Braking Distance at Higher Speeds

Doubling speed increases stopping distance approximately fourfold.

Assisting Heavy Bleeding Victims

Apply direct pressure to the wound and elevate the injury if possible to control bleeding.### First Aid for Wounds
Apply direct pressure to stop heavy bleeding while waiting for professional help.
Use materials like gauze from a first-aid kit, clothing, or your hand if no other options are available.

Pre-Trip Inspection for Vehicle Safety

Secure all loose items in the vehicle to prevent distractions while driving.
Confirm possession of all required paperwork essential for driving.
Turn off unnecessary lights to conserve battery and avoid drawing attention.
