We are planning for a road trip to Tirupati from Chennai. We plan to rent a self-driven car for this trip as it seems to be the cheaper option compared to hiring a taxi. We are looking for information about the best possible route to travel between Chennai and Tirupati. Anyone who has recently travelled from Chennai to Tirupati please update on the road condition and driving direction. Also, please let us know whether it is safe to travel in night. We are a family of 6 with women and kids, so road safety is a concern. Thanks in advance for your help.
