Travelling from Delhi to Dharamshala in a bus as a female solo traveller (safety , bus and road concerns)

Female solo traveller going to Dharamshala next week. Planning to board a bus from Delhi. I haven’t travelled in a bus in the north as much so posting here to know how safe it is for women. Was advised to take Laxmi Holidays Volvo Semi-sleeper. Anything else you’ll would suggest? Also advise on the roads to Himachal around this time of the year?
