New Jersey’s phased rollout of the new Alcotest 9510 breathalyzer has begun, replacing the older Alcotest 7110 model—and it could significantly affect DWI cases statewide. As defense attorneys, we’re closely analyzing how this update may create challenges (or opportunities) for defendants. Here’s what you need to know:
Key Changes in the Alcotest 9510
The upgraded device, approved by NJ’s Supreme Court in 2023, includes:
Faster results and wireless data transmission to prosecutors. New “dual-test” methodology, requiring two breath samples (like its predecessor). Alleged improvements in accuracy and interference detection (e.g., for mouth alcohol).
Potential Legal Implications
While prosecutors may argue the 9510 is more reliable, defense attorneys can scrutinize:
Calibration and maintenance records: New devices often face rollout glitches.
Operator training errors: Police must be certified on the 9510—mistakes could invalidate tests.
Challengeable software: Past Alcotest models had flaws (e.g., firmware bugs affecting readings).
What This Means for Drivers
If you’re charged with a DWI based on a 9510 test:
Don’t assume the result is airtight. Even “improved” tech can be challenged.
Act fast: Request additional evidence (maintenance logs, officer training records).
Consult a DWI specialist: Precedent is still being set—strategic defenses matter now more than ever.
