House committee substitute to the 1st edition makes the following changes.

Amends new GS 20-219.3A, by specifying that the prohibition on immobilizing a commercial vehicle using a device such as a boot is when it is done for the purpose of parking enforcement. Makes violations a Class 2 misdemeanor (was, deemed a misdemeanor). 

Amends new GS 20-219.15, requiring a tower of a nonconsensual tow or a tow under the direction of a law-enforcement officer (was, government-initiated tow) to promptly return any commercial cargo towed by the tower to the owner of the commercial cargo or to a designee of the owner upon request (request was not required under the previous edition). Allows for trailers that are towed to be exchanged for another trailer of similar type that is in working condition and was manufactured within five years of the manufacturing date of the original trailer, or newer, as arranged by the commercial cargo owner (was, a trailer in equal or better condition so that the owner of the trailer containing the commercial cargo gets the cargo back).
