The issue of whether left-turn protection on any or all intersection approaches should be provided is difficult to determine but can be simplified by some guidelines:i
1. Left-turn protection should be used for left-turn volumes of more than 250 vehicles per hour (vph).i
2. For volumes less than 250 vph, the opposing volumes and number of lanes should be considered.i
3. For small left-turn volumes less than 100 vph, left protection is rarely used.i
