What Affects Rates in Houston
- Harris County processes over 10,000 DWI cases annually, creating 2–4 week delays between conviction and SR-22 filing eligibility. Occupational license hearings at the Downtown Criminal Courthouse on Franklin Street move faster with documented SR-22 proof in hand. Failure to file SR-22 within 30 days of the court order extends your suspension automatically.
- Texas requires IID installation for all DWI convictions. Houston has 40+ certified IID vendors, most clustered along the I-10 Energy Corridor, Westchase, and Near Northside. Installation runs $75–$150, monthly monitoring $65–$90. Your occupational license restricts you to IID-equipped vehicles only.
- Houston's lack of comprehensive rail transit means occupational license routes must cover I-10 (Katy Freeway), I-45 (North and Gulf Freeway), US-59 (Southwest Freeway), and Loop 610. Judges approve work, school, medical, and essential household errands, but recreational routes are denied. Document your route with employer address and childcare locations.
- One-third of Houston DWI defendants no longer own a vehicle post-arrest due to impound, sale, or repo. Non-owner SR-22 policies cost $35–$75/month and satisfy Texas SR-22 filing requirements without a registered vehicle. You cannot drive any vehicle without explicit owner permission and IID installation.
