A cap on hospital parking charges must be introduced throughout Scotland "without delay", the health secretary has said.
Health Secretary Nicola Sturgeon met campaigners against charges
New guidance outlining the £3 maximum charge per day has been issued to health boards across Scotland.
Nicola Sturgeon said parking should be free at most NHS sites.
She said: "I hope that this guidance reassures staff, patients and visitors ... that we see fairer, more affordable schemes in place across Scotland."
Car parking schemes which impose uniform charges across a number of sites are "not acceptable" under the new guidance.
Ms Sturgeon added: "Evidence from a number of health boards shows that charging high daily rates is not the only way to discourage or control unauthorised parking.
"I agree with the group's recommendation that all other avenues should be explored before charges are introduced."
The guidance follows an independent review by a panel of experts.
