There are ~7 bicycle relevant laws working their way through the Maryland Congress right now. WABA has a write up on 5 on them.
Legalizing HAWK signals in Maryland- SB 338
The right to bicycle through crosswalks – SB 337
Lowering speed limits in Montgomery County – HB 337 and HB 332
Task Force to Study Bicycle Safety on Maryland Highways – SB 142
BikeAA is following these and 2 others pretty closely. So far, the only one to move forward is HB 11 which outlaws Coal Rolling which "is the practice of modifying a diesel engine to increase the amount of fuel entering the engine in order to emit an under-aspirated sooty exhaust that visibly pollutes the air." None have been voted down yet either.
The two other bills are
Bicycles, Play Vehicles, and Unicycles on crosswalks and sidewalks are like pedestrians - SB 925
Making coal rolling illegal - HB 11
WABA has a form that Maryland voters can use to send a message to Maryland legislators.
[B' Spokes: I will mention that am amazed that we have to pursue legislation to get MDOT to do a pedestrian friendly thing like HAWK signals. 23% of Maryland road fatalities are pedestrian (less then 10 states have higher numbers). Didn't we have to do something similar to get MDOT to declare bik/PED priority areas?]
