Motorists could have their blood type added to their Louisiana driver’s license under a bill approved Tuesday morning by the House Transportation Committee.

The proposal, House Bill 37, next faces action in the full House.

State Rep. Terry Brown, No Party-Colfax, emphasized that the information would be voluntary.

No additional charge would be added.

The blood type would be placed below the photograph of the license holder.

The option would also apply to state-issued identification cards.
