"It keeps down the accidents. They all stay in one group. They try not to get strung out. But also, the other vehicles, the motoring public, can identify them as a part of that procession," said Sgt. David Walker of the Lufkin Police Department.
Funeral processions are usually escorted by a police officer, a Sheriff's Deputy, or a County Constable. When a procession is being escorted, that official has authority to control traffic.
"If they are authorized to direct traffic and hold up that traffic as a peace officer, then you are required to stay and yield right of way until the way is cleared of the funeral procession," said Sgt. Walker.
In Texas, there is no law stating that you must pull over for a funeral procession, but many drivers do so out of respect for the deceased.
