NETTCP Transportation Safety & Inspection 4

Question 1

Under NETTCP safety standards, when a technician identifies a cracked or broken leaf spring on a commercial vehicle, what is the immediate action?

Accepted Answer

Place vehicle out of service — broken spring is an OOS condition

Answer

A cracked or broken leaf spring is an FMCSA out-of-service condition because it critically compromises vehicle stability and control.

Question 2

A transportation technician is conducting a Level I roadside inspection. Which of the following is included in a Level I inspection?

Accepted Answer

Driver and vehicle inspection including all major systems

Answer

A Level I North American Standard Inspection is the most comprehensive, covering both the driver's documentation and a thorough vehicle inspection of all major safety systems.

Question 3

What is the maximum allowable out-of-adjustment condition for an S-cam brake before it becomes an out-of-service violation on a vehicle with a 6-inch stroke chamber at full rated pressure?

Accepted Answer

The stroke limit specified on the chamber's data plate

Answer

Brake adjustment limits are determined by the stroke length marked on the brake chamber's data plate, and exceeding that limit is an out-of-service condition.

Question 4

When inspecting cargo securement, a technician finds a tiedown strap with a working load limit (WLL) of 5,000 lbs securing a 12,000 lb piece of equipment. Assuming only one strap is used, how should this be classified?

Accepted Answer

Non-compliant — insufficient aggregate WLL for the cargo weight

Answer

FMCSA requires aggregate WLL of tiedowns to equal at least half the cargo weight, so a 12,000 lb load requires at least 6,000 lbs aggregate WLL.

Question 5

A technician conducting a brake inspection finds the brake lining thickness is 1/4 inch on a disc brake rotor-style system. Under FMCSA criteria, how should this be evaluated?

Accepted Answer

Out of service — disc brake lining must be at least 1/8 inch above wear indicator

Answer

FMCSA out-of-service criteria specify disc brake lining thickness must not be worn to the wear indicator or less than 1/8 inch, so 1/4 inch should be evaluated against specific wear indicator markings.
