Is it against the law in India to drive a car without an internal rearview mirror, even if it has both outside mirrors? Do Indian traffic rules mandate having an internal mirror, or can we rely solely on the external ones?

Indian traffic rules do not explicitly mention an internal rearview mirror as mandatory. However, driving with only external mirrors could be considered a safety hazard, making it indirectly against the law as it could lead to prosecution under negligence provisions. It is advisable to have both internal and external mirrors for safe driving.
