Two equipment rules – one which makes permanent an existing requirement for antilock brake systems, the other regarding turbochargers – are now federal regulations.
The Federal Motor Carrier Safety Administration published confirmations of the effective dates of these direct final rules in the Nov. 3 Federal Register.
FMCSA confirmed Nov. 22 as the effective date of the direct final rule titled “Parts and Accessories Necessary for Safe Operation: Antilock Brake Systems.” This rule, published Sept. 21, made permanent the existing requirement that trailers with an antilock brake system be equipped with an external malfunction indicator lamp.
The agency also confirmed Nov. 19 is the effective date of the direct final rule titled
“Compliance with Interstate Motor Carrier Noise Emission Standards: Exhaust Systems.” That rule, published Sept. 20, eliminates turbochargers from the list of equipment considered to be noise dissipative devices.
When the two direct final rules were published, the agency advised that unless it received written adverse comment or notice of intent to submit adverse comment by deadline dates, it would provide notices confirming effective dates. These direct final rule procedures were used because the rules were not considered to be controversial.
Affected trucks include model year 2008-2018 Freightliner Cascadia and Western Star 4700, 4900, 5700 and 6900 trucks. DTNA says after hard brake applications, the brake light pressure switch may not activate the brake lights with the light application of the brake pedal.
