The regulator also said general insurance companies cannot force individuals to purchase personal accident policies along with motor insurance.
Of late, it has come to notice of the IRDAI that some general insurance companies "having tie-ups with a particular motor dealer are not accepting motor business, if it is sourced by any other agent or intermediary".
Similar issue has also been observed where some insurers offer personal accident policies along with such motor policies, the IRDAI said.
Also, companies should ensure that no clause/agreement/ tie-up in variation with the the directions should be entered into by any insurer with any motor dealers/ manufacturers.
"It should also be ensured that all existing agreements confirm with the above direction," the Insurance Regulatory and Development Authority of India said in the circular.
