All legislators have “town halls” where they sit in an office and meet and talk to constituents. Show up dressed in a nice suit or your best ‘business casual’ attire (I can’t emphasize enough the need to be ‘straight’ when meeting politicians or bureaucrats. They’re looking for a reason not to take you seriously, and if in your dress, demeanor, or style you give them a reason to…Sam Brown once said “Never offend people with style, when you can offend them with substance.”), shake their hands, and introduce yourself as someone who’s very concerned about traffic safety and would love to get some time with their staff to talk about the issue. Write a polite, grammatical, cleanly formatted letter to follow up. You’ll get handed off to a junior staff member, but the way that junior staff member becomes a senior staff member is by identifying and ‘owning’ issues that become important to the legislator. Work with them to help this happen, and the two of you can accomplish a lot.
