ConclusionsConclusions
Overall, reductions in every crash category, red light Overall, reductions in every crash category, red light violation, rear end, and injury crashes make RLC violation, rear end, and injury crashes make RLC Enforcement an important tool for public safetyEnforcement an important tool for public safety
