Highway had a reasonable start at some metro multiplexes while it was slow generally. The opening is very similar to Hasee Toh Phasee released a couple of weeks back but with a lower screen count. The film opened at around 20-25% on average and if it has double the occupancy in the evening which is easily possible it will get a total that gives it a chance of success.
These films like Highway are more about what they do in the evening unless the opening is total washout which is not the case here. The opening is okay for the film if it can grow.
