Reaction to Tailgating
- Increase the following distance with the vehicle in front to enhance safety.
Driving in Fog
- Best practice is to avoid driving in fog whenever possible due to reduced visibility.
Hot Weather Effects
- Extremely hot weather leads to increased tire pressure which can affect handling.
Hand Valve Use
- Hand valve helps prevent trucks from rolling backwards when starting from a stop.
Mirror Adjustment
- Ensure part of the vehicle is visible in the mirrors for optimal visibility.
Straight-Line Backing Exercise
- Driver may exit the vehicle once to check its position during the backing exercise.
Rim Safety
- Rims that have undergone welding repairs are considered unsafe for use.
Multi-Speed Axles
- Multi-speed axles and auxiliary transmissions provide additional gearing options for driving.
Fuel Record Retention
- Fuel records for IFTA quarterly fuel use tax must be kept for four years.
Tire Load Rating Location
- Tire load rating can be found on the sidewall of each tire.
Preventing Vehicle Rollback
- Partially engaging the clutch before releasing the brake can help prevent rollback when starting.
Gross Vehicle Weight Rating (GVWR)
- GVWR is the maximum weight specified by the manufacturer for a fully loaded vehicle.
Hydraulic Brake Check
- Check hydraulic brakes by pumping the brake pedal three times and applying firm pressure for five seconds; pedal should remain firm.
Air Storage Tanks Function
- Air storage tanks hold enough air reserve for multiple brake uses if the compressor stops working.
ABS and Steering Control
- When ABS is only equipped on the tractor, it enhances steering control during braking.
Fifth Wheel Inspection
- Ensure locking jaws around the kingpin are fully closed during pre-trip inspection of the fifth wheel gap.
Air Compressor Governor Role
- The air compressor governor regulates when air is pumped into the storage tanks.
Required Equipment on Air Tanks
- Every air tank on air-braked vehicles must have a check valve installed.
Hydroplaning Response
- In the event of hydroplaning, do not apply the brakes to regain control safely.
ABS Warning Light
- Vehicles equipped with ABS utilize a yellow light to indicate improper system function.
Hazardous Materials Endorsement Denial
- Not being a lawful permanent resident of the U.S. is a valid reason for denial of a hazardous materials endorsement.
Lane Usage Evaluation
- During on-road tests, moving to the left-most lane unnecessarily is considered poor lane usage.
Loading Cargo Responsibility
- While others can load cargo, the driver maintains ultimate responsibility for cargo safety.
Header Board Requirements
- If present, the header board must be sufficiently strong to secure the cargo safely.
Emergency Equipment Standards
- Acceptable pieces of emergency equipment do not include 4 yellow squares during vehicle inspections.
Passive Railroad Crossings
- Passive crossings lack control devices to manage traffic at the crossing site.
