Abstract
With population explosion, automobiles have also exploded and so has pollution due to vehicular emissions. Road-side plants and highway vegetation are the first targets of these vehicular emissions. This review briefly presents a snapshot of how vehicular emission can affect plants. On the contrary, the positive perspective of how road-side plants may be able to affect and influence the harmful effects of vehicular emissions has also been discussed. Ways and means by which plants can become potential bio indicators of air pollution have also been speculated. The fact that the nanocarbon particulate aspect of automobile pollutants and their interactions with road-side plants and more so on road-side agricultural crops, has not been appropriately investigated has been raised as a key concern. The need to arrive at mitigation methods to identify permanent solutions to these rising concerns has been highlighted.

This review presents the impact of automobile-based effects on highway/roadside plants
Air pollution due to vehicular emission [37,115,116] affects all varieties of road-side plants
Summary
The recent decades have seen a gradual increase in the global population from 7.4 billion in 2016 to 7.7 billion in 2019, 7.8 billion in 2020 to 7.9 billion in 2021. 5 decades ago about 53 million automobiles were approximated, this has boomed to 500 million in 2000 and every year about 19 million vehicles are added [2]. It is an understandable increase in two wheelers, since they are an economic mode of transport. This review presents the impact of automobile-based effects on highway/roadside highway plants are subjected to, has been briefly discussed. The existing knowledge on the physiological and morphological changes these plants have on reducing automobile-based effects has been discussed. The practical implementation of this acquired has been speculated and discussed
