The legal limits
Will your film pass in District of Columbia?
A trooper's meter reads the film and the glass. Factory glass runs about 78% VLT, so net VLT = film × glass — which is why "35% film" can fail a 35% state. Common shades over factory glass:
| Film | Meters at | Front side | Back side | Rear |
|---|---|---|---|---|
| 70% | 54.6% VLT | Fail | Pass | Pass |
| 50% | 39.0% VLT | Fail | Fail | Fail |
| 35% | 27.3% VLT | Fail | Fail | Fail |
| 20% | 15.6% VLT | Fail | Fail | Fail |
| 5% | 3.9% VLT | Fail | Fail | Fail |
