A double solid yellow line means you cannot pass or cross into oncoming traffic under Illinois law (625 ILCS 5/11-303). These two parallel yellow lines separate opposing traffic lanes and indicate that passing in either direction is prohibited. Crossing a double yellow line is illegal except when turning into a driveway, alley, or private road—and only if done safely without impeding traffic.

Fault Determination in Double Yellow Line Accidents
If you’re in a car accident involving a double yellow line violation, fault is typically clear:
| Scenario | Who Is At Fault? | Fault Percentage | Legal Basis |
|---|---|---|---|
| Driver crosses double yellow to pass, hits oncoming car | Crossing driver | 100% | Negligence per se (statutory violation) |
| Driver crosses to turn left, hits oncoming motorcycle | Turning driver | Usually 100% | Failure to yield right-of-way |
| Both drivers partially in wrong lane | Shared fault | Varies (50/50 possible) | Comparative negligence |
| Driver avoids obstacle, crosses yellow, hits oncoming car | Usually crossing driver | 70-100% | Emergency doctrine may reduce fault |
| Drunk driver crosses double yellow | Drunk driver | 100% | DUI + traffic violation |

- Spinal cord injuries – Compression fractures, herniated discs, paralysis
- Broken bones – Legs, arms, ribs, pelvis from impact forces
- Internal organ damage – Spleen, liver, kidney trauma
- Chest injuries – Steering wheel impact, seatbelt injuries
- Facial injuries – Airbag burns, glass lacerations
- Wrongful death – Head-on collisions have highest fatality rate of any crash type
