A new law will go into effect next Tuesday that involves Missouri motorists .  Effective Tuesday all motorists in Missouri must change lanes and yield for stopped Transportation Agency Vehicles displaying flashing amber or white lights. The state plans to erect some 120 signs throughout Missouri to remind motorists of the new law.  According to the Missouri Department of Transportation, some 24-hundred employees work near roadsides in the state each and every day which was a direct reason for the new law being passed. This will give more space between vehicular traffic and work zones and hopefully reduce the amount of work place injuries and deaths in the Sho-Me State.
