ALINACAK ÖNLEMLER VE ÖNERİLER

Uykusuz ve yorgun araç kullanmaya karşı alınacak önlemler ya doğrudan uykusuz araç kullanmamayı amaçlayan ya da uykusuzluk meydana geldikten sonraki durumu düzeltmeye yöneliktir. Yeterli uyku uyuyarak uykusuzluğu önlemek herhangi bir telafi edici önlemden hem daha kolaydır hem de daha etkilidir. Uyku geldikten sonra alınan önlemlerin etkisi çok fazla sürmemektedir. En fazla sürücülerin uyuyabilecek bir yer bulmalarına yetecek kadar bir süre için etkili olabilmektedir.

Kafein alımı, radyo dinlemek, araçtan inip kısa bir yürüyüş yapmak, camı açmak vb gibi geçici önlemler kesinlikle iyi bir uyku alışkanlığının yerini almamalı ve uykusuz sürücülerin varacakları yere güvenle varmalarını sağlayacak etkili stratejiler olarak algılanmamalıdır.
