There are numerous ways to safely communicate your presence.

Question: For how long will you lose your CDL driving privileges if you are convicted of a second DUI offense?

Life

Due to nationwide drunk driving laws, a second DUI offense in either a CMV or non-CMV vehicle will cause you to lose your CDL for life. (See Federal Motor Carrier Safety Regulations Part 383.51, issued by the Federal Motor Carrier Safety Administration (FMCSA)). Your first offense is a wake-up call and a chance to get help, but your second offense is going to mean unemployment. If you get a DUI, seek help before you lose your salary and your future.
