Nocturnal head-on collisions remain a recurring problem on National Road No. 4 connecting Mahajanga to the capital. According to drivers and passengers, one of the reasons for frequent nighttime accidents is the glare caused by LED lighting used by certain vehicles traveling on national roads at night, including minibuses and trucks. Glare from poorly adjusted or non-compliant LED headlights is increasingly being identified as an aggravating factor in nighttime accidents. In Madagascar, the use of these lamps is prohibited. The majority of public transport vehicles and minibuses operating on RN4 at night are equipped with this lighting. "The use of dazzling, blinding, or non-approved LED headlights (non-standard or modified white lights) is strictly forbidden on roads at night. All lighting must be compliant and properly oriented to avoid disturbing other road users," stipulate Road Code Law No. 2017-002 and Decree 93-894 which strictly regulate lighting. The ATT must take strict measures on the use of these LED headlights, as poorly oriented LED or xenon headlights generate very intense light (white/bluish light). When facing oncoming traffic, they temporarily blind drivers, preventing them from correctly estimating distances or anticipating the presence of another vehicle on a curve or straight road. Last Saturday, two transport vehicles affiliated with a national cooperative, Volkswagen Sprinter type, collided around 11:30 p.m. at kilometer 256+700 in the fokontany of Begisa, rural municipality of Antsiafabositra, Maevatanana district. "Glare is often combined with excessive speeding by public transport vehicles (minibuses) traveling at night, making evasion impossible. The two minibuses were certainly traveling at high speed and collided inevitably," said a minibus driver. Vero Andrianarisoa
