Traffic Safety

Responsibilities

Traffic Safety is responsible for day-to-day traffic signal, signage, striping and safety operations. We focus on addressing reported traffic concerns, as well as preventative maintenance, to maximize safety for all road users. We strive to make driving in unincorporated Adams County safe and efficient.

Traffic Calming Program

Speed Humps are traffic calming facilities which encourage motorists to reduce their operating speeds while passing over an installation. Vehicles may safely cross speed humps at 15-20 mph. Speed bumps are designed for vehicles to cross at 5 mph or slower, and are commonly used in parking lots. Speed bumps are not considered a safe installation for use on local roads. For more information about the Adams County Speed Hump Program, please follow the links below:

• Speed Hump Program Requirements
• Speed Hump Request Form

Cautionary signs are non-standard warning signs that are intended to raise motorist awareness of young roadway users. Adams County will install specific cautionary signs in locations that meet the eligibility criteria described in the Cautionary Sign program requirements:
