Unit  4  Understanding  and  Avoiding  Hazardous  Substances  Copyright  Goodheart-Willcox  Co.,  Inc.  280  Alcohol  Use  and  Accidents  Alcohol  slows  down  the  central  nervous  system,  which  affects  the  body  in  various  ways.  Figure  9.8  shows  some  of  these  effects.  These  include  a  decrease  in  reaction  time,  difficulty  coordinating  movements,  and  a  decreased  ability  to  plan  and  use  good  judgment.  As  a  result,  people  who  have  been  drinking  are  more  likely  to  engage  in  unsafe  behaviors  that  often  cause  accidents.  Motor  Vehicle  Accidents  In  every  state,  there  are  laws  to  prevent  driving  under  the  influence  of  alcohol  or  drugs.  Despite  this  fact,  driving  after  alcohol  use  leads  to  many  deaths  in  the  United  States  (Figure  9.9).  In  fact,  over  10,000  people  die  each  year  in  alcohol-related  motor  vehicle  crashes.  Therefore,  a  young  person  should  never  get  in  a  car  with  a  driver  who  is  intoxicated.  People  who  drink  and  drive  can  face  legal  consequences  for  their  actions.  Adults  who  drive  with  a  BAC  of  0.08  or  above  are  driving  under  the  influence  (DUI),  which  is  against  the  law.  In  some  states,  this  may  also  be  called  driving  while  intoxicated  (DWI).  If  a  driver  receives  a  DUI  or  DWI,  his  or  her  license  may  be  suspended,  or  taken  away  for  several  months.  This  driver  may  also  have  to  pay  a  fine,  perform  community  service,  or  spend  time  in  jail.  Alcohol’s  Effects  on  the  Central  Nervous  System  When  alcohol  slows  down  the  nervous  system,  the  body  experiences  •  decreased  reaction  time  •  difficulty  coordinating  movements  •  decreased  ability  to  plan  or  problem  solve  •  decreased  use  of  good  judgment  BlueRingMedia/Shutterstock.com  Figure  9.8  As  alcohol  filters  into  the  brain  and  bloodstream,  it  affects  a  person’s  ability  to  think  and  move  quickly  and  correctly.  More  than  Drunk  Driving  30%  of  car  accident  deaths  are  caused  by  Glass  and  keys:  iStock.com/dehooks  Figure  9.9  Because  of  alcohol’s  effects  on  the  body’s  reflexes,  motor  skills,  and  alertness,  driving  after  drinking  alcohol  frequently  results  in  deadly  car  accidents.  What  is  the  legal  term  for  a  person  who  has  consumed  too  much  alcohol  before  driving  a  vehicle?
