🚗 We all love a clean car, but washing it in a driveway or on the street can wash oil, heavy metals, and brake dust into storm drains and local waterways. Use a commercial car wash, choose eco-friendly products, and prevent leaks. https://t.co/AmcDQAIol1 💧 #CleanWaterCA

Less than one quarter of the U.S. population lives in rural areas, yet rural roads are disproportionately deadly. 🛣️❌

This National Rural Road Safety Awareness Week – and every week – remind yourself:
🚜 Expect slow-moving farm machinery
📉 Slow down before sharp curves
🪨 Watch for loose gravel and soft shoulders
