"We're responding 24 hours a day as needed," said Greene County Rescue Squad Chief, Curtis Davenport.
When lights are flashing, and sirens are sounding, for those responding, there is no time to waste.
"It has to be a serious call, it has to be a life threatening call," said Paragould Police Sergeant, Marcus Walker.
Getting to those emergencies can be difficult, officials say when people don't know or just don't follow the rules of the road.
"They need to pull over to the right as soon as they can do so safely," said Walker.
Paragould Police Sergeant Marcus Walker says, it's important drivers move to the right as quickly and safely as possible, because emergency vehicles use the left lane to pass.
"If they go to the left suddenly, then we're involved in an accident," said Walker.
"It can very well be a life-saving incident that we're called to, and we need to get there as quickly as possible," said Davenport.
Although strictly volunteers, members of the Greene County Rescue Squad are trained for emergency situations. Chief Curtis Davenport says they are also mandated to take an emergency vehicle driving class. Oftentimes driving their own vehicles, which are equipped with red flashing lights and sirens, to a scene.
"We need the same courtesy that you give to the police department, state police, fire trucks, ambulance, or a rescue truck," said Davenport.
Davenport says it's imperative drivers pay attention to their surroundings on the road and follow the rules. In addition, he says if you see one emergency vehicle pass with lights and sirens on--chances are, it's not the only one.
"So be looking for those vehicles and pull over plenty ahead of time because we may be going to save a life that's connected to you in some way," said Davenport.
