What comes out of the tailpipe ends up in the air people breathe, and children and older adults feel it first.

Motor vehicles are major contributors to ground level ozone.

Vehicle emissions rise unless a vehicle is carefully maintained, and as a vehicle ages its performance and fuel economy fall away.

A car that is looked after burns less and puts out less, which shows up in the fuel bill too.

Although today’s new vehicles emit fewer pollutants than older vehicles, their emission levels will increase unless they are carefully maintained.

Kentucky advises drivers to avoid quick starts and stops, drive smoothly at moderate speeds, and pace their driving to the traffic and signal timing.

Smooth driving uses less fuel and it is also what keeps a car out of the one behind.

Avoid quick starts and stops. Drive smoothly and at moderate speeds.
